<P>PROBLEM TO BE SOLVED: To provide a fuel cell system in which excellent cooling efficiency and insulation are secured without causing a large sizing and a short lifetime of an ion exchanger. <P>SOLUTION: The fuel cell system 1 has a cooling passage 73 connecting between a fuel cell 20 and a radiator C2, and a cooling water is circulated between the fuel cell 20 and the radiator C2 by a pump C1. The cooling passage 73 is composed of an insulated fuel cell side piping part 73A and a grounded radiator side piping part 73B, and the radiator side piping part 73B has a larger diameter than that of the fuel cell side piping part 73A. <P>COPYRIGHT: (C)2009,JPO&INPIT |
