The oxidizing gas supply is stopped during the catalyst activation treatment, and the output voltage of the fuel cell is linearly decreased toward the reduction target voltage. Once the interruption condition of the activation treatment has been satisfied, a voltage command value of the converter is returned to a standby voltage and, after waiting till the output voltage of the fuel cell returns to the vicinity of the standby voltage, the compressor is operated to start the supply of the oxidizing gas, and the catalyst activation treatment is completed. As a result, overcharging of the battery caused by rapid increase in the output power of the fuel cell is avoided.
