<P>PROBLEM TO BE SOLVED: To provide a fuel cell system which hardly exerts adverse influence on power generating characteristics of a fuel cell and on the charging/ discharging characteristics of a capacitor. <P>SOLUTION: A charging current, flowing from the fuel cell 21 to a capacitor 25, and a regenerative current from a motor drive circuit 29 to the capacitor 25 are controlled by a switching device 28A and an HBC controller 33. Herewith, even although the fuel cell 21 and capacitor 25 are separately connected in parallel to the motor drive circuit 29, the discharge current and regenerative current flowing from the fuel cell 21 and motor drive circuit 29 to the capacitor 25 can be restricted. Thereby, this fuel cell system hardly exerts adverse influence on the power generating characteristics of the fuel cell 21 and on the charging/discharging characteristics of the capacitor 25. <P>COPYRIGHT: (C)2003,JPO |
