DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013 is being examined under the first inventor to file provisions of the AIA .
The Applicant’s amendment filed on 4/2/2026 was received. Claims 1-5, 7-11, 14-19 were amended. Claims 6, 13, 20 were cancelled. Claims 5, 12, 19 were withdrawn.
The text of those sections of Title 35, U.S.C. code not included in this action can be found in the prior Office action issued on 1/8/2026.
Claim Interpretation
Regarding to claims 1, 8, 15: Applicant alleged the limitation of “an end of the fuel supply line of the fuel cell power plant cooling system (structure) is connected to a fuel supply line of a second fuel cell power plant cooling system (structure)” can be supported in paragraphs [0014] and [0075]. However, it is coolant supply lines (402a, 404a),instead of fuel supply lines, to be connected to coolant supply lines (402b, 404b) of a second fuel cell power plant cooling system (fig. 4B and 4C in the instant application). For purposes of examination, Examiner uses fuel supply lines, instead of coolant supply lines, in the instant limitation as recited in the claims. Examiner interprets “an end of the fuel supply line of the fuel cell power plant cooling system (structure) is connected to a fuel supply line of a second fuel cell power plant cooling system (structure)” as “an end of the fuel supply line of the fuel cell power plant system (structure) is connected to a fuel supply line of a second fuel cell power plant system (structure); wherein each of the fuel power plant systems (structures) has a cooling system”.
Claim Objections
The claim objection on claims 6, 13, 20 are withdrawn because Applicant canceled claims 6, 13, 20.

Claim Rejections - 35 USC § 103
Claim 3 remains rejected under 35 U.S.C. 103 as being unpatentable over Zhou et al. (US 20230010307 A1) as applied in claim 2 above, and further in view of Osborne et al. (US 20100183936 A1).
Regarding to claim 3: Zhou et al. disclose a large-scale proton exchange membrane fuel cell power station process system as described in paragraph 5 above.

The modular fuel cell power system comprises a fuel cell stack (12) (par. 11, fig. 1). The fuel cell stack can be disposed within a vehicle (par. 11) (equivalent to the fuel cell systems are repurposed from vehicle fuel cells). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to use the fuel cell stack in a vehicle of Osborne et al. for the cell stack of Zhou et al. because Osborne et al. teach that fuel cell stack can be either within a vehicle or outside a vehicle (par. 11).

Response to Amendment
Applicant’s arguments filed on 04/02/2026 have been fully considered but they are not persuasive. Applicant primarily argues:
Zhou discloses a distributed cell stack module connected to a cooling system, rather than a first cooling system connected to a second cooling system, as required by amended claim 1. The other prior arts, Osbourne and Kitamoto, fail to remedy the shortcomings of Zhou.
In response:
Applicant’s arguments are not persuasive. Zhou discloses a first cell stack module (FC101A-FCnA) and a second cell stack module (FC101B-FCnB) (a fist cell stack module (FC101A-FCnA) and a second cell stack module (FC101B-FCnB) are equivalent to two power units of a first fuel cell power plant system) are connected to a first cooling water inlet branch pipe (PL401) and a second cooling water inlet branch pipe (PL403), respectively (par. 36, fig. 3) (a combination of a first cell stack module (FC101A-FCnA), a second cell stack module (FC101B-FCnB), a first cooling water inlet branch pipe (PL401), and a second cooling water inlet branch pipe is equivalent to a first cooling system). Zhou further discloses a Nth cell stack module (an Nth cell stack module is equivalent to a power unit of a second fuel cell power plant system) is connected to an Nth cooling water inlet branch pipe (par. 36) (a combination of an Nth cell stack module and an Nth cooling water inlet branch pipe is equivalent to a second cooling system). As the fuel supply main pipe (PL270) connected to the first cell stack module (FC101A-FCnA), the second cell stack module (FC101B-FCnB), and the Nth cell stack module, the fuel supply main pipe (PL270) is connected the first cooling system and the second cooling system.
