<P>PROBLEM TO BE SOLVED: To obtain the maximum cell output in a short time when starting a fuel cell system at low temperatures. <P>SOLUTION: Since the temperature in the vicinity of an air electrode and a fuel electrode of a fuel cell 10 is higher than the cooling water outlet temperature, the temperature of the air electrode and the fuel electrode is above 0°C when the cooling water outlet temperature exceeds 0°C, and the fuel cell 10 is in a temperature condition wherein moisture is not frozen. Therefore, if humidification is started when the cooling water temperature has exceeded 0°C, an electrolyte film in the fuel cell 10 can be humidified while avoiding freezing of moisture in the fuel cell 10 when starting it at low temperatures, and the maximum cell output can be obtained in a short time even when starting the fuel cell system at low temperatures. <P>COPYRIGHT: (C)2004,JPO |
