PROBLEM TO BE SOLVED: To quickly raise the temperature of a secondary battery in a fuel cell system.SOLUTION: A fuel cell system comprises a driving motor, a fuel cell, an auxiliary machine, a secondary battery, a temperature sensor, a current sensor, and a control unit. The driving motor generates driving force of a mobile body, and regenerates kinetic energy of the mobile body to electric energy. The fuel cell supplies driving power to the driving motor. The auxiliary machine is used for power generation by the fuel cell. The secondary battery supplies driving power to the driving motor and the auxiliary machine. The temperature sensor measures the temperature of the secondary battery. The current sensor measures discharge current of the secondary battery. When the temperature measured by the temperature sensor is less than a predetermined value, the control unit controls discharging of the secondary battery by driving the driving motor or the auxiliary machine and charging of the secondary battery by power generation of the fuel cell or regeneration of the driving motor.SELECTED DRAWING: Figure 4
