`DETAILED ACTION
`
`Notice of Pre-AlA or AIA Status
`
`1.
`
`The present application, filed on or after March 16, 2013, is being examined under the first
`
`inventor to file provisions of the AIA.
`
`Response to Amendment
`
`2.
`
`Acknowledgment is made to Applicant’s claim amendments received 5 January 2024. Claims 1-
`
`29 are currently pending of which claim 1 is currently amended and claim 29 is new.
`
`Claim Rejections - 35 USC § 102
`
`3.
`
`In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102
`
`and 103 (or as subject to pre-AlA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory
`
`basis (i.e., changing from AIA to pre-AlA) for the rejection will not be considered a new ground of
`
`rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same
`
`under either status.
`
`4.
`
`The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis
`
`for the rejections under this section made in this Office action:
`
`A person shall be entitled to a patent unless —
`
`(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale,
`or otherwise available to the public before the effective filing date of the claimed invention.
`
`5.
`
`Claims 1, 2, 3, 22, 23, 24 and 27 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by
`
`US Patent Application Publication No. 2003/0196893 to McElroyet al. (McElroy).
`
`6.
`
`As to claim 1, McElroy teaches a hydrogen system comprising a water electrolysis cell (10b), an
`
`electrochemical hydrogen pump (10a) that increases a pressure of hydrogen containing gas produced by
`
`the water electrolysis apparatus (10b), a gas flow path (80) that supplies the hydrogen containing gas
`
`

`

`Application/Control Number: 16/953,195
`Art Unit: 1794
`
`Page 3
`
`producedbythe water electrolysis apparatus (10b) to the electrochemical hydrogen pump (10a).
`
`McElroy further teaches that the apparatus comprises a heat exchanger (58) which transfers heat
`
`betweenafirst flow path (82) comprising water, thus at least partially liquid, that collects waste heat of
`
`the water electrolysis, and a second flow path (81) which transfers heat with the electrochemical
`
`hydrogen pump (10a), thus an apparatus specifically configured such that, under the appropriate
`
`operating conditions, the electrochemical hydrogen pump is heated by heat exchangewiththe first
`
`medium after collecting the waste heat of the water electrolysis cell, for example, at start up when the
`
`hydrogen pump is not operating at a high temperature and the stream (81)is at a lower temperature
`
`than stream (82) (Paragraphs 0050-0051; Figure 3).
`
`7.
`
`As to claim 2, McElroy teaches the apparatus of claim 1. McElroy further teaches that thefirst
`
`flow path (82) is arranged in such a waythatthe first heat medium perform heat exchange with each of
`
`the water electrolysis cell (10b) and the electrochemical pump (10a) and after the first heat medium
`
`collects waste heat of the water electrolysis cell (10b) the first heat medium performs heat exchange
`
`with the electrochemical hydrogen pump (10a),i.e. the first heat medium exiting the electrolysis cell
`
`(10b) flow from the cell (10b) into the thermal conduction conduit (82) and exchanges heat within a
`
`heat exchanger (58) where heat is exchanged with a water feed line which is sent to the electrolysis cell
`
`(10b) and through a bleed line (78) to the pump to provide heat to both the electrolysis cell (10b) and
`
`the pump (10a), the heat exchanger also exchanging heat with a thermal conduction conduit (81) in
`
`communication with the pump (10a) (Paragraphs 0050-0051; Figure 3).
`
`8.
`
`As to claim 3, McElroy teaches the apparatus of claim 1. McElroy further teaches that the first
`
`head medium in the first flow path (82)is liquid water for water electrolysis that was supplied to the
`
`waterelectrolysis apparatus (10b) (Paragraphs 0050-0051; Figure 3).
`
`9.
`
`As to claim 22, McElroy teaches the apparatus of claim 1. McElroy further teaches that the
`
`apparatus comprises a heat exchanger (58) at which heat exchangeis performed between the first heat
`
`

`

`Application/Control Number: 16/953,195
`Art Unit: 1794
`
`Page 4
`
`medium (in flow path (82)) and a second heat medium thatis a liquid a second flow path (81) through
`
`which the second heat medium flows, wherein the second heat medium performs heat exchange with
`
`the electrochemical hydrogen pump (10a) after performing heat exchangeat the heat exchanger (58)
`
`(Paragraphs 0050-0051; Figure 3).
`
`10.
`
`As to claim 23, McElroy teaches the apparatus of claim 22. The heat exchanger (58) can be
`
`considered a second thermal storage, in that the heat exchanger, at least temporarily stores the second
`
`heat medium.
`
`11.
`
`As to claim 24, McElroy teaches the apparatus of claim 23. McElroy further teaches that the
`
`heat exchanger (58) performs heat exchange between the first and second medium with a third medium
`
`in a third flow path (via conduit (56)) (Paragraphs 0050-0051; Figure 3). The heat exchanger (58) can
`
`thus be considered a third thermal storage, in that the heat exchanger, at least temporarily stores the
`
`third heat medium.
`
`12.
`
`As to claim 27, McElroy teaches the apparatus of claim 1. McElroy further teaches that the
`
`apparatus comprises a tank (86) that is provided on the gas flow path and stores the hydrogen
`
`containing gas (Paragraphs 0050-0051; Figure 3).
`
`13.
`
`Claims 1, 2, 4, 27 and 29 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by McElroy
`
`under a second interpretation.
`
`14.
`
`As to claim 1, McElroy teaches a hydrogen system comprising a water electrolysis cell (10b), an
`
`electrochemical hydrogen pump (10a) that increases a pressure of hydrogen containing gas produced by
`
`the water electrolysis apparatus (10b), a gas flow path (80) that supplies the hydrogen containing gas
`
`producedby the water electrolysis apparatus (10b) to the electrochemical hydrogen pump (10a).
`
`15.
`
`McElroy further teaches that the apparatus comprises a heat exchanger (58) which transfers
`
`heat betweena first flow path (81) through whicha first heat medium thatis liquid flows, the first heat
`
`

`

`Application/Control Number: 16/953,195
`Art Unit: 1794
`
`Page 5
`
`medium transferring heat between a fluid stream (82) that collects waste heat of the water electrolysis
`
`and the first heat medium through the heat exchanger (58), thus an apparatus specifically configured
`
`such that, under the appropriate operating conditions, the electrochemical hydrogen pump is heated by
`
`heat exchange with the first medium after collecting the waste heat of the water electrolysis cell, for
`
`example, at start up when the hydrogen pump is not operating at a high temperature and the stream
`
`(81) is at a lower temperature than stream (82) (Paragraphs 0050-0051; Figure 3).
`
`16.
`
`As to claim 2, McElroy teaches the apparatus of claim 1. McElroy further teaches that thefirst
`
`flow path (81) is arranged in such a waythatthe first heat medium perform heat exchange with each of
`
`the water electrolysis cell (10b) and the electrochemical pump (10a) and after the first heat medium
`
`collects waste heat of the water electrolysis cell (10b) the first heat medium performs heat exchange
`
`with the electrochemical hydrogen pump (10a),i.e. the first heat medium flows through thermal
`
`conduction conduit (81) into a heat exchanger (58) where heat is exchanged with a stream (82) carrying
`
`waste heat from the electrolysis cell (10b) and then the first medium flow through thermal conduction
`
`conduit (81) to the pump (10a) (Paragraphs 0050-0051; Figure 3).
`
`17.
`
`As to claim 4, McElroy teaches the apparatus of claim 1. McElroy further teaches that thefirst
`
`heat medium is a coolant which cools the stream from the electrolysis cell (82) which is different from
`
`liquid water for water electrolysis supplied to the water electrolysis apparatus (Paragraphs 0050-0051;
`
`Figure 3).
`
`18.
`
`As to claim 27, McElroy teaches the apparatus of claim 1. McElroy further teaches that the
`
`apparatus comprises a tank (86) that is provided on the gas flow path and stores the hydrogen
`
`containing gas (Paragraphs 0050-0051; Figure 3).
`
`19.
`
`As to claim 29, McElroy teaches the apparatus of claim 1. McElroy further teaches that the first

`
`Claim Rejections - 35 USC § 103
`
`20.
`
`In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102
`
`and 103 (or as subject to pre-AlA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory
`
`basis (i.e., changing from AIA to pre-AlA) for the rejection will not be considered a new ground of
`
`rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same
`
`under either status.
`
`21.
`
`The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections
`
`set forth in this Office action:
`
`A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is
`not identically disclosed as set forth in section 102, if the differences between the claimed invention
`and the prior art are such that the claimed invention as a whole would have been obvious before the
`effective filing date of the claimed invention to a person having ordinaryskill in the art to which the
`claimed invention pertains. Patentability shall not be negated by the manner in which the invention
`was made.
`
`22.
`
`The factual inquiries for establishing a background for determining obviousness under 35 U.S.C.
`
`103 are summarized as follows:
`
`1. Determining the scope and contentsofthe prior art.
`
`2. Ascertaining the differences between the prior art and the claims at issue.
`
`3. Resolving the level of ordinary skill in the pertinent art.
`
`4. Considering objective evidence present in the application indicating obviousness or
`
`nonobviousness.
`
`23.
`
`This application currently namesjoint inventors. In considering patentability of the claims the
`
`examiner presumesthat the subject matter of the various claims was commonly ownedas of the
`
`effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised
`
`of the obligation under 37 CFR 1.56 to point out the inventor and effectivefiling dates of each claim that
`
`was not commonly ownedas of the effective filing date of the later invention in order for the examiner
`
`

`

`Application/Control Number: 16/953,195
`Art Unit: 1794
`
`Page 7
`
`to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art
`
`against the later invention.
`
`24.
`
`Claims 21 and 25 are rejected under 35 U.S.C. 103 as being unpatentable over McElroy,in the
`
`first interpretation, as applied to claims 1 and 22 above,and further in view of US Patent Application
`
`Publication No. 2020/0316522 to Rheaume (Rheaume).
`
`25.
`
`As to claim 21, McElroy teaches the apparatus of claim 1. McElroy teaches that the first heat
`
`medium is supplied to the first flow path; however,is silent as to specifically how. However, Rneaume
`
`also discusses the supply of fluid for heat exchangein electrolysis apparatus and teachesthat the fluid
`
`can be supplied through a speed-controlled pump (Paragraph 0048). Therefore, it would have been
`
`obvious to one of ordinaryskill in the art at the time offiling to deliver the first heat medium to thefirst
`
`flow path utilizing a speed-controlled pump,a first deliverer, with the expectation of effectively
`
`delivering the fluid, thus a first deliverer capable of performing the functional language of “caused to
`
`start operation whenthe electrochemical hydrogen pump starts operation”.
`
`26.
`
`As to claim 25, McElroy teaches the apparatus of claim 1. McElroy teaches that the second heat
`
`medium is supplied to the second flow path; however,is silent as to specifically how. However,
`
`Rheaume also discusses the supply of fluid for heat exchange in electrolysis apparatus and teaches that
`
`the fluid can be supplied through a speed-controlled pump (Paragraph 0048). Therefore, it would have
`
`been obvious to one of ordinary skill in the art at the time offiling to deliver the second heat medium to
`
`the second flow pathutilizing a speed controlled pump, a second deliverer, connected with a controller
`
`of some sort, with the expectation of effectively delivering the fluid, thus a second deliverer and
`
`controller capable of performing the functional language of “causes the second deliverer to start
`
`operation when the electrochemical hydrogen pump starts operation”.

`
`Claims 1, 2, 3,5, 6, 8 and 22 are rejected under 35 U.S.C. 103 as being unpatentable over US
`
`Patent Application Publication No. 2016/0122882 to Oomura et al. (Oomura) in view of McElroy.
`
`28.
`
`As to claim 1, Oomura teaches a hydrogen system comprising a water electrolysis apparatus
`
`comprising a water electrolysis cell (12), a gas flow path that supplies hydrogen containing gas produced
`
`by the water electrolysis apparatus to a hydrogen compression unit (15) and a first flow path through
`
`whicha first heat medium thatis a liquid (raw water inlet) and has collected waste heat from
`
`electrolysis (through use as a cooling liquid in the cooling unit (13)) flows, wherein the hydrogen
`
`compression unit (15) performs heat exchangewith the first heat medium having collected waste heat
`
`of the water electrolysis cell (Paragraphs 0019-0033; Figure 1).
`
`29.
`
`However, Oomurafails to teach that the hydrogen compression unit comprises an
`
`electrochemical hydrogen pump, Oomurafailing to give specific configuration details for the hydrogen
`
`compressor, instead focusing on capturing heat from the compression. However, McElroy also discusses
`
`the compression of electrolytically produced hydrogen and teachesthat an effective compression unit
`
`from which heat can be captured comprises an electrochemical hydrogen pump (Paragraphs 0003 and
`
`0050-0052). Therefore, it would have been obvious to one of ordinary skill in the art at the time offiling
`
`to utilize an electrochemical hydrogen pump for the compression unit of Oomura with the reasonable
`
`expectation of effectively compressing the hydrogen and capturing the heat therefrom. Thus,in
`
`combination, an apparatus specifically configured such that, under the appropriate operating
`
`conditions, the electrochemical hydrogen pump is heated by heat exchange withthe first medium after
`
`collecting the waste heat of the water electrolysis cell, for example, at start up when the hydrogen
`
`pump is not operating at a high temperature and is at a lower temperature than the steam generator.
`
`30.
`
`As to claim 2, the combination of Oomura and McElroy teaches the apparatus of claim 1.
`
`Oomura further teachesthat the first flow path (raw water flow path) is arranged in such a way that the
`
`first heat medium, the raw water, performs heat exchangewith the water electrolysis cell and the
`
`

`

`Application/Control Number: 16/953,195
`Art Unit: 1794
`
`Page 9
`
`electrochemical hydrogen pump and after the first head medium collects waste heat of the water
`
`electrolysis cell the first heat medium performs heat exchange with the electrochemical hydrogen
`
`pump,i.e. the raw water is utilized to cool the hydrogen stream exiting the electrolysis cell, thus
`
`collecting waste heat of electrolysis ad then is sent to the steam generator for heat exchange with the
`
`electrochemical hydrogen pump of the combination (Paragraphs 0019-0033; Figure 1).
`
`31.
`
`As to claim 3, the combination of Qomura and McElroy teaches the apparatus of claim 1. As
`
`discussed above, the first heat medium is liquid water for water electrolysis supplied to the water
`
`electrolysis apparatus.
`
`32.
`
`As to claim 5, the combination of Oomura and McElroy teaches the apparatus of claim 1.
`
`Oomurafurther teaches that the apparatus comprises a gas-liquid separator (14) provided on the gas
`
`flow path, wherein the first head medium comprises liquid water separated from the hydrogen-
`
`containing gas by the gas liquid separator (14), the gas liquid separator sending this separated water,
`
`along with the raw water, to the cooling apparatus and then to the steam generator (11) the stream
`
`generator can be considered a reservoir in which the liquid water in the gas-liquid separator collects
`
`(Paragraphs 0019-0033; Figure 1).
`
`33.
`
`As to claim 6, the combination of Qomura and McElroy teaches the apparatus of claim 1.
`
`Oomurafurther teaches that the apparatus comprises a cooler (13) that cools the first heat medium
`
`(water sent through the electrolysis cell) having collected waste heat of the water electrolysis cell before
`
`the first heat medium performs heat exchange with the electrochemical pump,i.e. the water in the form
`
`of steams leavesthe cell, is cooled with fresh raw water, is separated from the hydrogen,utilized again
`
`in the cooling operation and then joined with the raw water which is sent to the stream generator for
`
`heat exchangewith the electrochemical pump of the combination (Paragraphs 0019-0033; Figure 1).
`
`34.
`
`As to claim 8, the combination of Qomura and McElroy teaches the apparatus of claim 1.
`
`Oomurafurther teaches that the apparatus comprises a cooler (13) that cools the hydrogen containing
`
`

`

`Application/Control Number: 16/953,195
`Art Unit: 1794
`
`Page 10
`
`gas flowing through the gas flow path upstream from the gas-liquid separator (14) (Paragraphs 0019-
`
`0033; Figure 1).
`
`35.
`
`As to claim 22, the combination of Oomura and McElroy teaches the apparatus of claim 1.
`
`Oomurafurther teaches that the apparatus comprises a heat exchanger, heat pump (17), performing
`
`heat exchange betweenthe first heat medium, the process water and a second heat medium, a
`
`refrigerant, that flow through a second flow path which performs heat exchange with the hydrogen
`
`pump (Paragraphs 0044-0048; Figure 2).
`
`36.
`
`Claims 7, 9, 10, 11, 12, 13, 20 and 26 are rejected under 35 U.S.C. 103 as being unpatentable
`
`over the combination of Oomura and McElroy as applied to claims 1, 5, 6, 8 and 22 above, and further in
`
`view of Rheaume.
`
`37.
`
`As to claim 7, the combination of Oomura and McElroy teaches the apparatus of claim 6.
`
`However, Oomurafails to further teach that the apparatus comprises a controller that causesthefirst
`
`cooler to increase a degree of cooling. However, Rheaume also discusses heat exchangein electrolysis
`
`apparatus and teaches that specific temperature requirements can be met by providing a controller that
`
`controls the degree of heat exchange based on temperature sensors provided to componentsof the
`
`system (Paragraph 0048). Therefore, it would have been obvious to one of ordinaryskill in the art at
`
`the time offiling to provide temperature sensors to the componentsof the system, including the
`
`electrochemical hydrogen pump, and connecting them with a controller to allow for increasing or
`
`decreasing the degree of heat exchangein the cooler based on the temperature sensors provided to
`
`system componentsincluding the electrochemical hydrogen pump in order to allow for the apparatus to
`
`meet specific temperature requirements as taught by Rheaume. Thus, rendering obvious a controller
`
`performing the functional language of “that causesthe first cooler to increase a degree of cooling when
`
`a temperature of an electrochemical cell included in the electrochemical hydrogen pump increases”.

`
`38.
`
`As to claim 9, the combination of Oomura and McElroy teaches the apparatus of claim 8.
`
`However, Oomurafails to further teach that the apparatus comprises a controller that causesthefirst
`
`cooler to increase a degree of cooling. However, Rheaume also discusses heat exchange in electrolysis
`
`apparatus and teaches that specific temperature requirements can be met by providing a controller that
`
`controls the degree of heat exchange based on temperature sensors provided to componentsof the
`
`system (Paragraph 0048). Therefore, it would have been obvious to one of ordinaryskill in the art at
`
`the time offiling to provide temperature sensors to the componentsof the system, including the
`
`electrochemical hydrogen pump, and connecting them with a controller to allow for increasing or
`
`decreasing the degree of heat exchangein the cooler based on the temperature sensors provided to
`
`system componentsincluding the electrochemical hydrogen pump in order to allow for the apparatus to
`
`meet specific temperature requirements as taught by Rheaume. Thus, rendering obvious a controller
`
`performing the functional language of “that causesthe first cooler to increase a degree of cooling when
`
`a temperature of an electrochemical cell included in the electrochemical hydrogen pump increases”.
`
`39.
`
`As to claim 10, the combination of Oomura and McElroy teaches the apparatus of claim 1.
`
`Oomurafurther teaches that the apparatus comprises a cooler (13) that cools the first heat medium
`
`(water sent through the electrolysis cell) having collected waste heat of the water electrolysis cell before
`
`the first heat medium performs heat exchange with the electrochemical pump,i.e. the water in the form
`
`of steams leaves the cell, is cooled with fresh raw water, is separated from the hydrogen,utilized again
`
`in the cooling operation and then joined with the raw water whichis sent to the stream generator for
`
`heat exchangewith the electrochemical pump of the combination (Paragraphs 0019-0033; Figure 1).
`
`However, Oomurafails to teach that the apparatus further comprises a branch path from the first flow
`
`path wherein the cooleris located. However, Rheaume also discusses heat exchangein fluid streams in
`
`electrolysis apparatus and teachesthat specific temperature requirements can be met by providing the
`
`heat exchangeto only a portion of the fluid stream and bypassing the other portion of the stream
`
`

`Art Unit: 1794
`
`Page 12
`
`wherein the amountof the stream passing to the heat exchange portion is controlled with control valves
`
`(Paragraph 0048). Therefore it would have been obvious to one of ordinaryskill in the art at the time of
`
`filing to modify the apparatus of the combination with a first branch path that branchesoff from the
`
`first flow path, passes throughthe first cooler, and mergesinto the first flow path and a first flow rate
`
`controller that controls a flow rate of the first heat medium flowing into the first branch path in order to
`
`allow for the apparatus to controllably meet specific temperature requirements as taught by Rheaume.
`
`40.
`
`As to claim 11, the combination of Oomura, McElroy and Rheaume teachesthe apparatus of
`
`claim 10. Rheaume further teaches that the control of the control valves operates based ona
`
`temperature sensed throughout componentsof the system (Paragraph 0048). Thus, rendering obvious
`
`an apparatus with a controller and temperature sensor on the system components, including the
`
`electrochemical hydrogen pump and thus an apparatus with a controller capable of performing the
`
`functional language of “when a temperatureof an electrochemical cell included in the electrochemical
`
`hydrogen pump increases, causesthefirst flow-rate controller to increase the flow rate of the first heat
`
`medium flowing into the first branch path”.
`
`41.
`
`As to claim 12, the combination of Oomura and McElroy teaches the apparatus of claim 5.
`
`Oomurafurther teaches that the apparatus comprises a cooler (13) that cools the hydrogen containing
`
`gas upstream of the gas liquid separator (14) (Paragraphs 0019-0033; Figure 1). However, Oomurafails
`
`to teach that the apparatus further comprises a branch path from the gas flow path wherein the cooler
`
`is located. However, Rheaume also discusses heat exchangein fluid streams in electrolysis apparatus
`
`and teaches that specific temperature requirements can be met by providing the heat exchange to only
`
`a portion of the fluid stream and bypassing the other portion of the stream wherein the amount of the
`
`stream passing to the heat exchangeportion is controlled with control valves (Paragraph 0048).
`
`Therefore it would have been obvious to one of ordinary skill in the art at the time of filing to modify the
`
`apparatus of the combination with a branch path that branchesoff from the gas flow path upstream of
`
`

`

`Application/Control Number: 16/953,195

`
`Page 13
`
`the gas liquid separator and mergesinto the gas flow path downstream of a position wherein the gas
`
`branch path branchesoff and upstream of the gas-liquid separator wherein the cooler is formed in this
`
`gas branch path, and a flow rate controller that controls a flow rate of the gas flowing into thefirst
`
`branch path in orderto allow for the apparatus to controllably meet specific temperature requirements
`
`as taught by Rheaume.
`
`42.
`
`As to claim 13, the combination of Oomura, McElroy and Rheaume teaches the apparatus of
`
`claim 12. Rheaume further teaches that the control of the control valves operates based ona
`
`temperature sensed throughout componentsof the system (Paragraph 0048). Thus, rendering obvious
`
`an apparatus with a controller and temperature sensor on the system components, including the
`
`electrochemical hydrogen pump and thus an apparatus with a controller capable of performing the
`
`functional language of “when a temperatureof an electrochemical cell included in the electrochemical
`
`hydrogen pump increases, causes the gas flow-rate controller to increase the flow rate of the hydrogen-
`
`containing gas flowing into the gas branch path.
`
`43.
`
`As to claim 20, the combination of Oomura and McElroy teaches the apparatus of claim 6. The
`
`first cooler can be considered a first thermal storage that, at least temporarily, stores heat collected
`
`from the first heat medium.
`
`44.
`
`As to claim 26, the combination of Oomura and McElroy teaches the apparatus of claim 22.
`
`However, Oomurafails to teach that the apparatus further comprises a bypass flow path that bypasses
`
`the heat exchanger and through which the first heat medium flows. However, Rheaume also discusses
`
`heat exchangein fluid streams in electrolysis apparatus and teachesthat specific temperature
`
`requirements can be metby providing the heat exchangeto only a portion of the fluid stream and
`
`bypassing the other portion of the stream wherein the amount of the stream passing to the heat
`
`exchangeportion is controlled with control valves (Paragraph 0048). Therefore, it would have been
`
`obvious to one of ordinaryskill in the art at the time offiling to modify the apparatus of the combination
`
`

`

`Application/Control Number: 16/953,195

`
`Page 14
`
`with a bypass flow path that bypasses the heat exchanger and through whichthe first head medium
`
`flows and a flow rate controller that controls a flow rate of the first heat medium flowing through the
`
`bypass flow pathin order to allow for the apparatus to controllably meet specific temperature
`
`requirements as taught by Rheaume.
`
`45.
`
`Rheaume further teachesthat the control of the control valves operates based ona
`
`temperature sensed throughout componentsof the system (Paragraph 0048). Thus, rendering obvious
`
`an apparatus with a controller and temperature sensor on the system components, including the
`
`electrochemical hydrogen pump and thus an apparatus with a controller capable of performing the
`
`functional language of “when a temperatureof an electrochemical cell included in the electrochemical
`
`hydrogen pump increase, cause the second flow-rate controller to increase the flow rate of the first heat
`
`medium flowing through the bypass flow path”.
`
`46.
`
`Claim 28 is rejected under 35 U.S.C. 103 as being unpatentable over McElroy as applied to claim
`
`1 above, and furtherin view of US Patent Application Publication No. 2014/0102911 to Kurashina etal.
`
`(Kurashina).
`
`47.
`
`As to claim 28, McElroy teaches the apparatus of claim 1. McElroy further teaches that the
`
`hydrogen is stored (86) downstream of the electrochemical hydrogen pump (10a) butfails to teach a
`
`specific use for the stored hydrogen (Paragraph 0051; Figure 3). However, Kurashina also discusses the
`
`use of hydrogen stored after production in and elect
