The disclosed control unit for a hybrid power generating system including a fuel cell and a storage battery backup includes an auxiliary controller for the fuel cell itself, and an output current controller for controlling the output current drawn from the fuel cell, whereby the storage battery can be charged for recovery within the shortest possible time to reach a target remaining charge capacity under charging conditions that do not cause deterioration of performance of the battery. The system is useful as the power supply in applications subject is sudden load fluctuations such as are encountered in a fork lift truck, for example.
