PROBLEM TO BE SOLVED: To prevent deterioration in a characteristic by a dew condensation water generated inside a battery in a high polymer electrolyte type fuel cell. SOLUTION: A pressure loss of a fuel or an oxidation gas in a flow inside of a fuel cell, an absolute value of a time difference value of a voltage generated in a single cell or a differentiation value are calculated and by performing value comparison with a presetting value defined beforehand. When the fuel or the oxidation gas has too much humidify, a temperature of a cell is raised, or an amount of humidifying of a gas is lowered. |
