A cooling system (100) of a fuel cell is provided with a main cooling flow passage (102) and a bypass cooling flow passage (104) which is arranged parallel with the main cooling flow passage (102) and diverts the same coolant, as flow passages through which coolant flows. A radiator (110) and a coolant circulation pump (WP) (130) and the like are arranged in the main cooling flow passage (102). Coolant from the main cooling flow passage (102) enters the bypass cooling flow passage (104) and reaches a second heat exchanger (120) via a case of a motor (50) of an ACP (48) and the like. At the second heat exchanger (120), heat exchange is also performed with a supply gas flow passage (80), after which the coolant returns to the main cooling flow passage (102). The manner in which the coolant is distributed can be changed depending on where the coolant is diverted from the main cooling flow passage (102) and the arrangement of the circulation pump (130). |
