摘要： A fuel cell system includes a fuel cell having a fuel gas flow path and an oxidant gas flow path; a compressor for supplying humidified air to the oxidant gas flow path; a back-pressure regulating valve for controlling pressure of humidified air in the oxidant gas flow path; a pressure sensor for measuring the pressure of the humidified air in the oxidant gas flow path; and a control section for controlling the compressor and the back-pressure regulating valve. In this system, the pressure of humidified air in the oxidant gas flow path is regulated to become equal or approximate to a target pressure by the back-pressure regulating valve. When the pressure difference between the pressure measured by the pressure sensor and the target pressure is larger than a predetermined pressure difference, the control section corrects operating conditions of the compressor, so that the measured pressure becomes the target pressure.

摘要： A start-up method for a fuel cell system that includes a fuel cell that carries out power generation by the electrochemical reaction between a fuel gas and the oxygen gas in the air; a fuel gas discharge path and a fuel gas supply path that are connected to the fuel cell; a fuel gas circulation path in which the fuel gas discharge path merges with the fuel gas supply path; and a purge valve provided on the fuel gas circulation path in order to discharge the circulating fuel gas from the fuel gas circulation path. The method includes the steps of opening the purge valve at the same time that the fuel gas is supplied to the fuel cell and replacing the nitrogen gas that originates in the air and is present in the fuel gas circulation path by fuel gas; and closing the purge valve after the nitrogen gas in the fuel gas circulation path has been replaced by the fuel gas.

摘要： A fuel cell system includes an idle stop unit, a discharger, a power-generation-state memory, and an initial-current-value setter. The idle stop unit is configured to stop a supply of the reactant gas to a fuel cell. The discharger is configured to allow the fuel cell to generate the electric power with the reactant gas remaining in the fuel cell after the idle stop unit stops the supply of the reactant gas and is configured to discharge electric current to a current receiver. The power-generation-state memory is configured to store a power-generation state of the fuel cell immediately before the idle stop unit stops the supply of the reactant gas. The initial-current-value setter is configured to set an initial current value of the fuel cell discharged by the discharger on a basis of the power-generation state of the fuel cell stored in the power-generation-state memory.
