<P>PROBLEM TO BE SOLVED: To supply stable power from a fuel cell and a secondary cell to a load. <P>SOLUTION: A fuel cell system comprises a fuel cell 1 to which fuel gas and oxidizing gas are supplied to generate electricity, an air supplying part 3 to supply the oxidizing gas to the fuel cell 1, a fuel gas supplying part to supply the fuel gas to the fuel cell 1, the secondary cell 7 which charges/discharges power, and a power distributer 4 which supplies power generated by the fuel cell to the load 5 for consumption while being supplied to the secondary cell 7 and charged and then discharged to be supplied to the load 5. A control unit 8 completes the warming-up of the fuel cell 1 and the secondary cell 7 at the starting time of the system, and starts the supply of power from the fuel cell 1 or the secondary cell 7 to the load 5. After that, even when a low output state continues, the control unit 8 allows stable power to be supplied to the load 5 by making the temperature of the fuel cell 1 raised when the power generating capacity of the fuel cell 1 decreases, and by making the temperature of the secondary cell 7 raised when the charge/discharge capacity of the secondary cell 7 decreases. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
