PROBLEM TO BE SOLVED: To improve the responsiveness of a pump motor to an indication of a demanded rotating speed.SOLUTION: In a fuel cell vehicle of the present invention comprising a fuel cell and a secondary cell, a driving motor and a pump motor are connected to each other via a power line so that the driving motor and the pump motor can receive and supply electric power from and to each other without via the reception and supply of the electric power from and to the secondary battery. A control device controlling the driving motor and the pump motor to operate determines an upper limit guard value of the torque of the pump motor on the basis of dischargeable electric power of the secondary battery, output electric power of the fuel cell and regenerative electric power of the driving motor, or determines a lower limit guard value of the torque of the pump motor on the basis of chargeable electric power of the secondary battery, the output electric power of the fuel cell and the drive electric power of the driving motor.SELECTED DRAWING: Figure 1 |
