PROBLEM TO BE SOLVED: To provide a cooling system for a fuel cell vehicle which enables a cooling air passage in a fuel cell system to be set at an optimum configuration for driving conditions, and an exhaust gas from the fuel cell system to be exhausted properly to the outside of the vehicle. SOLUTION: The system comprises a cooling duct 25 as a cooling air passage communicated in a fuel cell unit, a fan 33 arranged at one end of the cooling duct for sucking cooling air from the air passage, a plurality of suction/exhaust ducts 15 joined to the cooling duct communicated between devices for the fuel cell unit for sucking/exhausting an outside air, and a plurality of switching valves 35 installed at junctions between the cooling duct and each of the suction/ exhaust ducts for changing the cooling air passage. The atmospheric temperature of the plurality of devices arranged in the fuel cell unit is detected by a temperature sensor 41, and the plurality of switching valves 35 and the fan 33 are controlled by a controller 37 so as to set the cooling air passage at an optimum configuration according to a temperature signal. |
