<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of improving a life and enhancing the marketability of a fuel cell by curtailing burdens on an electrolyte film and the generation of noise caused by frequent scavenging treatment. <P>SOLUTION: After the fuel cell 1 generating power by the reaction of reactive gas stops power generation, the state of the fuel cell is monitored at preset intervals, and at that time, the inside of a flow channel of the reactive gas is scavenged by scavenging gas when the fuel cell is determined to be in a given state needing the scavenging. The first monitoring interval immediately after the stop of the power generation of the fuel cell 1 is decided in accordance with a temperature in the fuel cell 1 at the stop of the power generation and an ambient temperature at which the fuel cell 1 is placed, and a second monitoring interval and onward is renewed according to an ambient temperature after the previous monitoring interval. <P>COPYRIGHT: (C)2007,JPO&INPIT |
