Abstract
A fuel cell system uses, as an inlet sealing valve, an eccentric valve having a rubber seat provided with a seal part having such a shape as to increase the surface pressure of a portion in contact with a seal surface of a valve element when pressure in an air supply passage rises. Each of an outlet integration valve and a bypass valve is constituted of an eccentric valve basically identical in structure to the inlet sealing valve. When supply of air to a fuel cell stack is to be stopped during deceleration of a vehicle, a controller closes the inlet sealing valve and opens the bypass valve and, after the inlet sealing valve is fully closed, closes the bypass valve.
