<P>PROBLEM TO BE SOLVED: To reduce a supply amount of water as much as possible by constantly maintaining reforming conditions. <P>SOLUTION: The fuel cell system 10 is provided with a first heating mechanism 77a which supplies a part of an exhaust gas discharged from a fuel cell stack 12 as a heat source for directly heating a reforming device 22 to the reforming device 22; and a second heating mechanism 77b which supplies the residual of the exhaust gas to a heat exchanger 18 and uses the heat generated in the heat exchanger 18, as a heat source for indirectly heating the reforming device 22. Temperature sensors 130a-130d are mounted to the reforming device 22. The ratio of the amount of heat supplied to the reforming device 22 from the first/second heating mechanisms 77a, 77b is adjusted by adjusting an opening/closing valve 132 on the basis of the temperatures detected by the temperature sensors 130a-130d. <P>COPYRIGHT: (C)2007,JPO&INPIT |
