Abstract
The device comprises a main loop (18) for cooling the fuel cell (12) and a secondary loop (20) for cooling at least the motor (10). These two loops (18, 20) form part of the same circuit which is traversed by a single refrigerant fluid and which comprises a section (22) common to the two loops on which a common pump (24) is mounted, and at least one regulation valve (38) is provided which is suitable for sharing the refrigerant fluid between the loops (18, 20) according to a chosen law. Application to electric and hybrid vehicles.
