The fuel cell power supply device is equipped with a fuel cell 1 and the capacitor 2 connected in parallel; a voltage boosting means 3 having an input unit connected in parallel to the fuel cell and the capacitor 2, and an output unit connected to a PDU 4 of an electric motor 1, so as to boost the output voltage of the fuel cell 1 and the capacitor 2 and to supply electric power obtained from the boosted voltage to the PDU 4; a secondary battery 21 connected to the output unit of the voltage boosting means 3 via a voltage conversion means 20; and an electric power supply control means 30 which controls the operation of the voltage conversion means 20, so as to control the supply of electric power to the PDU4 from the secondary battery 21 via the voltage conversion means 20, and the charging of the secondary battery 21 by the supply of electric power to the secondary battery 21 from the voltage boosting means 3 via the voltage conversion means 20. By doing so, the fuel cell power supply device capable of maintaining high output and achieving down-sizing may be obtained. |
