FUEL CELL POWER GENERATION DEVICE

WIPO Patent Application WO/2006/040999

A1

A fuel cell power generation device (1) includes a fuel gas reservoir (3) for storing a fuel gas, i.e., substantially a hydrogen gas and supplying it; an air supply device (4) for supplying air; and a fuel cell (2) in which the fuel gas and the air are supplied to the anode and the cathode, respectively so that the chemical reaction between the supplied fuel gas and the air generates power. The fuel cell power generation device (1) seals the air in the cathode and consumes oxygen in the air while continuing power generation in that state so as to remove oxygen from the cathode. After this, power generation is stopped. After this, the fuel gas or a mixture of a fuel gas and an inactive gas is sealed in the anode. The gas remaining in the cathode is replaced by a fuel gas or a mixture of the fuel gas and the inactive gas. The fuel gas or mixed gas replaced is sealed in the cathode. After this, operation is stopped. During the stop period, the open voltage is maintained at not smaller than 0 V and not greater than 0.85 V.
