Device for regulating the temperature of an on-board fuel cell system on board a motor vehicle, comprising a circulation circuit (2) for a heat transfer fluid for the thermal regulation of the system, an electronic control unit (24) ), a pump (3) controlled by the electronic control unit (24), and a plurality of temperature sensors (4, 5, 6, 7) of which one (4) is placed at the output of the battery combustible. The circulation circuit (2) passes through the fuel cell (1) and a pre-anodic condenser (8), and comprises a first plurality of control valves (9, 10, 11, 12) controlled by the control unit electronics (24) to maintain, in nominal operation, a temperature (Topt) in the fuel cell (1) within a temperature range. |
