Abstract
A fuel cell system capable of learning its current-voltage characteristics precisely in a short time even when the current-voltage characteristics of a fuel cell varies due to reduction of a catalyst of an oxidizing agent electrode during the stop of operation of the fuel cell system. A controller () learns current-voltage characteristics of a fuel cell stack (), detects the amount of variation in voltage of current-voltage characteristics before a stop of power generation and those after restart of power generation, and corrects the learnt value of the current-voltage characteristics by the amount of variation in voltage.
