摘要： 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.

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 method for controlling the flow rate of an oxidizer in a fuel cell system having a fuel cell stack being supplied with fuel and the oxidizer, a compressor for supplying the oxidizer to the fuel cell stack, a back pressure valve for controlling pressure of the oxidizer, and a control device for controlling the fuel cell stack, the compressor, and the back pressure valve. The method includes the steps of calculating an oxidizer pressure command and an oxidizer flow rate command based on a given electrical current command, comparing a first flow rate that is defined as an upper limit of oxidizer flow rate and a second flow rate that is defined as a lower limit of oxidizer flow rate with the oxidizer flow rate command, and regulating the oxidizer flow rate command so as to be limited within a range from the second flow rate to the first flow rate.
