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： 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.
