Abstract
A power supply apparatus has a fuel cell unit as a source of input power. A control device limits the output of the fuel cell unit within an operating range of up to a maximum power point, even if a load power is not lower than the maximum power of said fuel cell unit. In addition to the fuel cell, a charge storing device is provided at the output side of the power supply apparatus. The charge storing device is capable of making up a shortage of power of the fuel cell.
