FUEL CELL POWER SUPPLY DEVICE
First Claim
1. A fuel cell power supply device, comprising:
- a fuel cell;
a voltage boosting means having an input unit connected in parallel to the fuel cell and an output unit connected to a first load, which boosts an output voltage of the fuel cell and supplies electric power obtained from the boosted voltage to the first load;
a storage means which is connected in parallel to the input unit or the output unit of the voltage boosting means;
a secondary battery which is connected to the output unit of the voltage boosting means via a voltage conversion means; and
an electric power supply control means which controls the operation of the voltage conversion means, in order to carry out the supply of electric power to the first load from the secondary battery via the voltage conversion means, and to carry out charging of the secondary battery by the supply of electric power to the secondary battery from the voltage boosting means via the voltage conversion means.

Abstract
A fuel cell power supply device can include a fuel cell, a voltage boosting device with an input unit connected to the fuel cell, and an output unit connected to a first load. The boosting device can boost an output voltage and supply electric power to the first load. A storage device is connected to the input unit or the output unit, and a secondary battery can be connected to the output unit of the voltage boosting device via a voltage conversion device. An electric power supply control device controls operation of the voltage conversation device, to carry out supply of electric power to the first load from the secondary battery via the voltage conversion unit. The electric power supply control device also carries out charging of the secondary battery by the supply of electric power to the secondary battery from the voltage boosting device via the voltage conversion device.
