<P>PROBLEM TO BE SOLVED: To provide a fuel cell system enhancing cooling performance. <P>SOLUTION: The fuel cell system is equipped with: an injection nozzle 55 supplying cooling water to a fuel cell stack 100; a supply passage 56 and a supply pump 61 supplying water to the injection nozzle 55; a water tank 531 supplying water to the supply pump 61; and a recovery pump 62 supplying water recovered from the fuel cell stack 100 to the water tank 531. The recovered water is cooled with a radiator 63 and then sent to the water tank 531. Since the temperature of the cooled recovered water is lower than that of simply recovered water, even if the cooling water is circulated for use, sufficient cooling effect is maintained. <P>COPYRIGHT: (C)2007,JPO&INPIT |
