摘要： In a method for stopping an operation of a fuel cell system, supply of a fuel gas to an anode side of a fuel cell provided in the fuel cell system is stopped. A fuel exhaust gas discharged from the fuel cell is recirculated to the anode side of the fuel cell. An oxidant-exhaust-gas discharge path through which an oxidant exhaust gas is to be discharged from the fuel cell is sealed at a downstream position of a connecting portion at which the oxidant-exhaust-gas discharge path is connected to an oxidant-exhaust-gas recirculation path. The oxidant exhaust gas is recirculated to a cathode side of the fuel cell through the oxidant-exhaust-gas recirculation path. Recirculation of the fuel exhaust gas is stopped. Recirculation of the oxidant exhaust gas is stopped. An oxidant-gas supply path through which an oxidant gas is to be supplied to the fuel cell is sealed.

摘要： Provided is a fuel cell system capable of preventing a fuel cell from being polarized at a high potential for a long time during start-up. A fuel cell system 1 includes a first injector 23A and a second injector 23B in a fuel gas inlet passage. When an ECU 60 determines that a power generation down time is equal to or more than a predetermined period at start-up of a fuel cell stack 10, a target pressure of hydrogen supplied to an anode passage 12 is set to be higher for supply than when the power generation down time is less than the predetermined period. In addition, as the power generation down time of the fuel cell stack 10 becomes longer, the target pressure is set to be higher. Also, a pressure increase in the fuel cell stack is set to be lower than that during ordinary power generation.
