Each of fuel cells ( 1 ) comprises an electrolyte membrane ( 10 ) which is held between an anode ( 2 ) and a cathode ( 3 ), and is caused to perform power generation by supplying hydrogen to the anode ( 2 ) from a hydrogen passage ( 11 ) and supplying air to the cathode ( 3 ) from an air passage ( 12 ). After the fuel cells ( 1 ) stop generating power, hydrogen which has been appropriately humidified on the basis of the temperature of the fuel cells ( 1 ) is supplied to the anode ( 2 ), and air which has been appropriately humidified on the basis of the temperature of the fuel cells ( 1 ) is supplied to the cathode ( 3 ). By means of this processing, condensed water inside the fuel cells ( 1 ) can be removed without causing the electrolyte membrane ( 10 ) to dry out, and hence the fuel cells ( 1 ) can be restarted easily in low temperatures. |
