Abstract
An electric power supply system 100 comprises a fuel cell system 20 including an FC auxiliary machine 23 that operates to causes fuel cells to generate an electric power, and a battery 10 that generates heat through discharging and charging. The electric power supply system 100 supplies the electric power to an electric load device 90. The electric power supply system 100 determines an operation state of the battery 10, and supplies the electric power discharged from the battery 10 to the FC auxiliary machine 23 of the fuel cell system 20 when it is determined that the battery 10 is a predetermined temperature or less. When it is determined that the battery 10 is in a charging state, the electric power supply system 100 reduces or stops the electric power supplied to the FC auxiliary machine 23.
