摘要： A fuel cell system equipped with a fuel cell, a pressure control unit, and an exhaust. The pressure control unit is provided on the fuel gas flow path in which the fuel gas to be supplied to the fuel cell flows, and it is able to control the pressure of the fuel gas to be supplied to the fuel cell. The exhaust valve is provided on the fuel exhaust gas flow path in which the fuel exhaust gas exhausted from the fuel cell flows, and when the valve is opened, at least a portion of the fuel exhaust gas can be exhausted to outside the fuel exhaust gas flow path. The pressure control unit is controlled, so that before opening the exhaust valve, the pressure of the fuel gas to be supplied to the fuel cell is decreased beyond what it was up to that point. Then, when the pressure of the fuel gas to be supplied to the fuel cell is the decreased first pressure, the exhaust valve is opened.
