Fuel cell comprising two stacks (6, 7) of electrochemical cells, a thermal management system formed by a circuit for circulating a heat-carrying fluid in each of the stacks (6, 7) fed in parallel, and an exterior circuit for circulating the heat-carrying fluid outside the stacks (6, 7), the outside circuit (12) comprising a first subcircuit (12.1) furnished with a heat exchanger (14) and a second subcircuit (12.2) connected directly to the input of the interior circuit (10), control valves (16, 17) for controlling the circulation of the heat-carrying fluid to one and/or the other of the subcircuits (12.1, 12.2) as a function of the temperature of said heat-carrying fluid on exit from each of the stacks, the second exterior subcircuit comprising means increasing its head loss so that it is close to or equal to that of the first exterior subcircuit. |
