PURPOSE:To prevent performance drop even in stop of power generation and make possible stabilized power generation for a long time by supplying dry gas in a gas chamber or in a sealed container when power generation is stopped to keep an atmosphere in contact with electrolyte dry. CONSTITUTION:A fuel cell main body 13 is set on a stand 24. Temperature of a fuel cell is raised with a supporting power source heater 25 and power generation is initiated at 500-650 deg.C. When power generation is stopped and the cell is kept at room temperature, an air inlet valve 26 is opened and dried gas such as inactive gas, air is introduced into a container from an inlet pipe 27, and an outlet valve 28 is opened to exhaust inside gas which is containing moisture from an outlet pipe 29. Supply of dried gas is continued till an inside atmosphere is dry. After inside gas becomes dry, valves 26 and 28 are closed and couplings 19 and 23 are closed to maintain the cell or container dry. |
