Abstract

A fuel cell/battery hybrid power system is disclosed which has a microprocessor based control system. The control system enables the fuel cell to be taken out of the system by a switch when its predetermined maximum desired energy output is about to be exceeded by load requirements. The battery is protected from overcharging by a switch which is activated responsive to the sensing of state of charge, load current and fuel cell current.
