PURPOSE:To make a device smaller and lighter, by providing an accumulation device which is connected to catalysts and which accumulates generated gas generated at the catalysts and also supplies the generated gas accumulated therein to the catalysts. CONSTITUTION:An accumulating device 34 is provided which is connected to a layer 2 of catalysts and which accumulates gas generated at the layer 2 of catalysts and also supplies the generated gas accumulated therein the layer 2 of the catalysts. After a fuel cell system has been stopped, therefore, purging can be performed to the layer 2 of catalysts using the generated gas accumulated in an accumulation tank 37. Outside air is restrained from entering the space around the layer 2 of catalysts by utilization of the generated gas so that the layer 2 of catalysts may be prevented from deteriorating, and there will thus be no necessity of storing specific inert gas in a bomb and the like. Besides, there will be no necessity of accumulating a large amount of generated gas in the accumulating device 34, but simply accumulating the generated gas therein each time the accumulating device is stopped. The device can thus be made smaller and lighter. |
