In a hybrid electric vehicle, the batteries store sufficient energy to supply the peak demand but the average demand is only 25% to 30% of the peak.

The fuel cell therefore needs to be capable of producing a steady ?trickle? charge at or slightly above the average power demand. For example, preliminary calculations show that a 0.25 kW fuel cell with a 0.75 kWhr battery pack hybrid system would provide more than the equivalent power of the 3kWhr lead-acid battery system currently used for golf carts indicating a 75% reduction in required battery capacity (and weight). And because peak demand is supplied by the battery, the output of the fuel cell needs to be 70% less than the vehicle's peak power requirements.
