In a fuel cell system, each of an inlet sealing valve and an outlet integration valve is provided with a valve seat including a valve hole and a seat surface formed on a circumferential edge of the valve hole, a valve element formed, on its outer periphery, with a seal surface corresponding to the seat surface, and a motor to move the valve element away from the valve seat upon receipt of electric power supplied from outside. The valve seat is provided with a seal member to seal between the valve element and the valve seat during non-operation of the motor. In an inlet-side bypass passage connected to an air supply passage by detouring around the inlet sealing valve, there are arranged an inlet-side bypass passage and an inlet bypass valve.
