A vehicle is described that can efficiently cool or heat a group of components, in view of appropriate operating temperature ranges of respective components configuring a fuel cell power supply system, while realizing saving of a mounting space in the vehicle and cost of the vehicle. The vehicle mounted with a fuel cell power supply system includes at least a fuel cell, and an accumulating unit includes a capacitor and a secondary battery connected to the fuel cell. A motor serves as a power source for the vehicle to which output sections of the fuel cell and the accumulating unit are connected. A PDU provided between the output sections and the motor. A component group of the power supply system, including the fuel cell, the accumulating unit, and the PDU, is cooled by a cooling medium which flows inside the vehicle, in order from one having a lowest heating generation amount.
