A power supply system is provided for supplying power to a first drive device and a second drive device functioning as a drive source of a moving body. A fuel cell and a storage battery device are connected via a power conversion device. The fuel cell can supply power to the first drive device and the storage battery device can supply power to the second drive device, respectively, without using the power conversion device. When an output request from the moving body is a normal output request, power is supplied to each of the drive devices by the fuel cell and the storage battery device, respectively. Only when power to be supplied to the first drive device as in the output request from the moving body is greater than an amount of power that can be generated by the fuel cell, that power supply from the storage battery device to the first drive device via the power conversion device is permitted. Thus, in a power supply device that is formed of a plurality of power supply devices connected via a power conversion device, it is possible to avoid, to the extent possible, decrease of efficiency of power supply to a drive device of a moving body. |
