Abstract: A controllable range of an air flow rate and an air pressure in a fuel cell system is calculated from air flow rates and air pressures when the air back pressure valve is fully open and fully closed. A target generation current is calculated from an accelerator position or an auxiliary unit to calculate a target air flow rate and a target air pressure as target values. If the target values are outside the controllable range, it is judged whether the target values exceed an upper limit the controllable range, the target values are decreased onto the upper limit, and if no, the target values are increased onto the lower limit of the controllable range.

Abstract: 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.

Abstract: The present invention provides a fuel cell system and a control method thereof that performs a scavenging process when the fuel cell is stopped, whereby stable electrical power production is ensured after startup, and faster startup is possible. The fuel cell system performs the scavenging process in which scavenging gas is supplied into an anode gas system when the fuel cell is stopped. When a startup request for the fuel cell is detected while the anode scavenging process is being performed, the concentration of hydrogen in the anode gas is detected, and then whether to continue the anode scavenging process and prohibit the fuel cell from starting, or to suspend the anode scavenging process and allow the fuel cell to start is determined based on this detected concentration of hydrogen in the anode gas system.
