PROBLEM TO BE SOLVED: To secure desired power supply efficiency of a plurality of external feeder circuits while preventing a configuration from becoming complicated.SOLUTION: A first external power supply device 12 is connectable between a fuel cell stack 21 and a voltage regulator 23, and a second external power supply device 13 is connectable between the voltage regulator 23 and a battery 22. An ECU (electronic control unit) 61 controls voltage conversion of the voltage regulator 23 such that the output voltage of the fuel cell stack 21 matches the proper voltage of the first external power supply device 12. The ECU 61 stores information about correspondence relation between the state of charge SOC and the output voltage of the battery 22, and controls the state of charge SOC such that the output voltage of the battery 22 matches the proper voltage of the second external power supply device 13. The ECU 61 matches the output power of the fuel cell stack 21 with supply voltage supplied from a fuel cell vehicle 11 to the first external power supply device 12 and the second external power supply device 13. |
