Abstract

An electric power supply systemcomprises a fuel cell systemincluding an FC auxiliary machinethat operates to causes fuel cells to generate an electric power, and a batterythat generates heat through discharging and charging. The electric power supply systemsupplies the electric power to an electric load device. The electric power supply systemdetermines an operation state of the battery, and supplies the electric power discharged from the batteryto the FC auxiliary machineof the fuel cell systemwhen it is determined that the batteryis a predetermined temperature or less. When it is determined that the batteryis in a charging state, the electric power supply systemreduces or stops the electric power supplied to the FC auxiliary machine
