<P>PROBLEM TO BE SOLVED: To provide a fuel cell system without any possibility of deterioration in a service life of a fuel cell. <P>SOLUTION: A fuel cell system is built as a system in which a fuel cell stack 1 and a rechargeable battery 3 are provided in parallel, and includes the fuel cell stack 1, a fuel feeder 2 feeding the fuel to the fuel cell stack 1, the electric storage device 3, and a DC/DC converter 4 converting the output voltage of the rechargeable battery 3 into a predetermined voltage and outputting it. This predetermined voltage is equal to or higher than the output voltage of the fuel cell stack 1 as obtained when the fuel cell stack 1 outputs the maximum output electric power. <P>COPYRIGHT: (C)2007,JPO&INPIT |
