FUEL CELL POWER SOURCE DEVICE

Japanese Patent JP3662872

B2

PROBLEM TO BE SOLVED: To provide a fuel cell power source device of high power efficiency through the use of a fuel cell and a double-layer capacitor in a directly coupled state.
SOLUTION: In a given output state, for instance, in a state of Ifc=I1, voltage value V2 of a fuel cell after load fluctuation is found based on composite output characteristics of the fuel cell and a double-layer capacitor with equilibrium position U over current voltage characteristics of the fuel cell in the output state and a prescribed load fluctuation band ΔI, and a current value Ifc2' corresponding to the above voltage value is derived based on the current voltage characteristics of the fuel cell, then, equilibrium reaction gas supply volume Qa1 corresponding to the current value Ifc2' is found. Reaction gas exceeding the equilibrium reaction gas supply volume Qa1 is supplied to the fuel cell as reaction gas supply volume in the output state.
