    摘要： Deterioration at the start-up and deterioration during the leaving period are suppressed in a good balance. As a system shutdown process, a controller (30) causes consumption of the air (oxygen) present in an oxidant electrode of a fuel cell stack (1) (oxygen consumption control). Further, after the termination of the oxygen consumption control, the controller (30) performs control to set a medium pressure hydrogen valve (13) and a hydrogen pressure adjustment valve (14) in a closed state. The controller (30) thereby causes hydrogen to be held in a passage located between the medium pressure hydrogen valve (13) and the hydrogen pressure adjustment valve (14). During a system shutdown period, a predetermined amount of hydrogen (medium pressure hydrogen) held in the hydrogen supply passage (L1) at a position between the medium pressure hydrogen valve (13) and the hydrogen pressure adjustment valve (14) can be supplied to the fuel electrode of the fuel cell stack (1) through a bypass passage (L2).

    摘要： A fuel cell system includes a fuel cell having an anode, a cathode, and an electrolyte membrane disposed therebetween. An oxidant gas supplying device supplies oxidant gas to the cathode, an oxidant gas backpressure regulating device regulates the pressure of the oxidant gas at the cathode according to a valve opening, and a pressure detecting device detects the oxidant gas pressure at the cathode. During a start-up fuel gas disposal process, a controller controls the oxidant gas supplying device to supply the oxidant gas at a standard oxidant gas flow, controls the valve opening of the oxidant gas backpressure regulating device to a first valve opening, and controls the valve opening of the oxidant gas backpressure regulating device to a second valve opening which is greater than the first valve opening when the oxidant gas pressure detected by the pressure detecting device reaches an elevation target pressure.
