With a fuel cell vehicle includes a fuel cell and a secondary battery, a drive motor and a pump motor are connected to each other via an electric power line so that the drive motor and the pump motor are capable of receiving and supplying electric power with each other without involving reception and supply of electric power with the secondary battery. The control device determines an upper-limit guard value of torque of the pump motor based on a dischargeable power of the secondary battery and an output power of the fuel cell, or determines a lower-limit guard value of torque of the pump motor based on a chargeable power of the secondary battery and an output power of the fuel cell.
