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 overdischarge through a switch.

A hybrid power source system for supplying electrical current to a load and for controlling the amount of current supplied in response to current demand from the load, comprising: a primary electrical energy source couplable to the load through a first switch means associated therewith and having a predetermined maximum desired power output; first energy storage means couplable to the load in parallel with the primary electrical power source through a second switch means associated therewith; second energy storage means couplable to the load in parallel with the primary electrical power source through third switch means; either said primary electrical energy source, said first, and said second energy storage means or combinations thereof being connected to the load in parallel to supply current to the load depending upon whether said first, said second or said third switch means or a combination thereof is approximately energized; load current sensing means for sensing the current flowing into the load; and control means responsive to said load current sensing means for selectively energizing either said first, second or third switch means in a manner such that the current demand on said primary electrical energy source is maintained at or below approximately its predetermined maximum desired power output level.
