    摘要： A fuel cell system and an idle stop controlling method for the fuel cell system. The fuel cell system includes: a fuel gas supply means for supplying fuel gas; an oxidant gas supply means for supplying oxidant gas; a fuel cell to which the fuel gas and the oxidant gas are supplied for generation of electricity; an idle stop means for stopping generation of electricity by the fuel cell to perform idle stop; and an unstable state detection means for detecting whether the generation of electricity by the fuel cell is unstable. If the unstable state detection means detects that generation of electricity by the fuel cell is unstable, idle stop by the idle stop means is prohibited so that the fuel cell continues to generate electricity.

    摘要： In an FC system of an FC vehicle, if a control device determines that conditions of an idling power generation suppression mode of a FC are satisfied, the control device sets the voltage of the FC to a predetermined voltage value outside a voltage range where an oxidation-reduction of platinum proceeds, and controls a reactant gas supply apparatus to change a supply amount of air such that the FC has an output in accordance with the electric power required by a load.

    摘要： A current limiting system for fuel cells includes a target current limit value setting device which sets a target current limit value for limiting the generated current taken out from the fuel cell stack in accordance with the cell voltage, and a current limit value setting device which sets a current limit value by replacing a present current limit value with the target current limit value when a difference between the present current limit value and the generated current value becomes smaller than a first predetermined value. The system also includes an output device which outputs the current limit value either to a current limiter for limiting the generated current in accordance with the current limit value or to an electric power consumption controller for controlling electric power consumption of loads that consume the generated current.

    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.
