Abstract:
1. A fuel cell system, comprising: a fuel cell including a pair of opposing electrodes having an electrolyte and a catalyst; an operation control device for controlling an operation of the fuel cell at a usual operation point to output a power in response to a demand for power generation; and a judgment device programmed to judge whether or not an operation to recover deterioration of the catalyst of an electrode of the pair of opposing electrodes is required, when the fuel cell is operated at the usual operation point, the operation control device being programmed to operate the fuel cell at a low-efficiency operation point which outputs the power equal to the demand for the power generation when the fuel cell is operated at the usual operation point, and which has a power loss from an open circuit voltage power larger than that of the usual operation point when the fuel cell is operated at the usual operation point and the judgment result of the judgment device is affirmative.
