<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of restraining aggravation of response of a switching valve, flow channel blocking or the like due to water of a supercooled state. <P>SOLUTION: The fuel cell system, provided with a fuel cell, a gas exhaust flow channel for passing gas exhausted from the fuel cell, a switching means switching the gas exhaust flow channel, and a storage part provided at the gas exhaust flow channel at an upstream side of the switching means for storing water flowing in the gas exhaust flow channel, is further provided with a temperature detecting means estimating or obtaining temperature of water stored in the storage part, a judgment means judging whether the water stored in the storage part is in a supercooled state based on temperature transition of water estimated or obtained by the temperature detecting means, and a freezing means freezing water stored in the storage part in case the water is judged to be in the supercooled state by the judgment means. <P>COPYRIGHT: (C)2009,JPO&INPIT |
