<P>PROBLEM TO BE SOLVED: To suppress the degradation of a catalyst and maintain an activity of a catalyst reaction in a fuel cell system with an anode gas flow path filled with purge gas when a system is not operated. <P>SOLUTION: Fuel gas is supplied from an entrance of the anode gas flow path provided between an anode electrode and a separator to a fuel cell stack 11, and, when an operation of the fuel cell system is stopped, at least a supplying means to circulate air gas purging the fuel gas in the anode gas flow path is structured by introducing the air gas from the exit side of the anode gas flow path. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
