<P>PROBLEM TO BE SOLVED: To reduce fuel consumption and enhance purge efficiency in a fuel cell system executing purge operation by controlling opening and closing of a purge valve. <P>SOLUTION: The fuel cell system 1 is equipped with a fuel cell 10; a supply passage 31 through which fuel gas flows from an fuel supply source 30 to the fuel cell 10; an injector 35 supplying gas by adjusting a gas state on the upstream side to the downstream side; an exhaust passage 32 through which fuel off-gas exhausted from the fuel cell 10 flows; a purge valve 37 for exhausting impurities in the exhaust passage to the outside; and a control means 4 controlling the injector 35 and the opening and closing operation of the purge valve 37. The control means 4 controls the injector 35 and the opening and closing operation of the purge valve 37 so as to set the supply amount of fuel gas from the injector 35 to the fuel cell 10 according to the opening and closing state of the purge valve 37. <P>COPYRIGHT: (C)2008,JPO&INPIT |
