<P>PROBLEM TO BE SOLVED: To cool a fuel cell system by simplifying the structure. <P>SOLUTION: In a cooling-water passage 41 connected to a radiator 40, a passage 41a for a fuel cell for circulating the cooling water from the radiator 40 via a fuel cell stack 20 to the radiator 40, and a passage 41b for heat generating apparatuses formed in parallel with the passage 41a for the fuel cell for circulating the cooling water from the radiator 40 via heat generating apparatuses 13 (an inverter part 32 of a PUC 30, an air supply unit 26, a heat exchanger 27 and a drive motor 35) to the radiator 40 are formed. In the passage 41b for heat generating apparatuses, the apparatuses are serially arranged, in the order starting from one having the smallest heat radiation amount in the circulation direction of the cooling water. A double-sided cooling mechanism, an air-cooling mechanism and an oil-cooling mechanism are formed in the inverter part 32, the heat exchanger 27 and the drive motor 35, respectively; and stable operations can be secured, even if the apparatuses are cooled by the cooling water at a temperature slightly higher than the normal. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
