<P>PROBLEM TO BE SOLVED: To share a radiator fan between a fuel cell and other heat radiation means by preventing a coolant from being excessively cooled while keeping performance of the fuel cell such as water balance and efficiency. <P>SOLUTION: A three-way valve 5 is used for regulating the coolant by branching it in a radiator direction and in a radiator bypass direction. A radiator 3 for circulating the coolant of the fuel cell, a high current cooling system radiator 3b and a capacitor 3c for an air conditioner share the radiator fan 4. A radiator fan drive discrimination means 15 discriminates whether the radiator fan 4 is operated by a request of a fuel cell 1 or operated by a request other than that of the fuel cell; and when it is discriminated that the radiator fan 4 is operated by the request other than that of the fuel cell 1, a three-way valve control means 12 sets the opening of the three-way valve 5 so as to increase the flow rate in the radiator bypass direction than that when the radiator fan is operated by the request of the fuel cell. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
