PROBLEM TO BE SOLVED: To provide a cooling system of a fuel cell which enables cooperative control between a cooling system of a fuel cell stack and other heat exchange systems.SOLUTION: A cooling system 100 of a fuel cell is equipped with: a main cooling flow passage 102 through which coolant flows; and a bypass cooling flow passage 104 which is arranged parallel with the main cooling flow passage 102 and diverts the same coolant. A radiator 110, a coolant circulation pump (WP) 130 and the like are arranged in the main cooling flow passage 102. The 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 and the like of a motor 50 of an air compressor (ACP) 48. At the second heat exchanger 120, heat exchange is also performed for 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 variously depending on how the coolant is diverted from the main cooling flow passage 102 and how the circulation pump 130 is arranged. |
