Abstract
A power supply system includes a fuel cell, a capacitor connected in parallel to the fuel cell, a voltage boost means for boosting output voltages from the fuel cell and the capacitor to supply the electric motor with electric power resulting from the boosted voltages, a voltage control means for further boosting an output voltage from the voltage boost means, a secondary battery connected to the voltage control means, an external power source connecting means connected to the one end of the voltage boost means and in parallel with the fuel cell and for receiving supply of electric power from an external power source, and an electronic control unit which charges the secondary battery from the external power source by controlling step-up ratios of the voltage boost means and the voltage control means such that a voltage applied to the secondary battery during the charging becomes a desired voltage.
