Abstract (en)

[origin: WO2022090173A1] The invention relates to a system for cooling a fuel cell assembly (10) of a transport vehicle, such as an aircraft, comprising: a coolant circulation loop (20); a cooling heat exchanger (24) configured to be able to provide heat exchanges between said loop (20) and a channel (25) for circulating a cooling air (26); a variable-speed pump (21) for supplying said cooling loop with coolant as a function of a measurement representative of the cooling need of said fuel cell assembly; for each fuel cell (10a, 10b, 10c) of said cell assembly, a 3-way valve (12a, 12b, 12c) for regulating the flow rate of coolant supplying this cell as a function of a measurement representative of the cooling need of this cell.
