Abstract
A hybrid fuel cell system comprising a solid-oxide fuel cell system, a proton exchange membrane fuel cell system, a hydrocarbon reformer and a hydrogen separator. A large PEM provides output power, such as motive power for a vehicle, using hydrogen storage that may be resupplied from a separate hydrogen refilling station or from the onboard reformer. The SOFC is preferably small and provides heat and exhaust water that, when recycled into the reformer, allow the reformer to operate endothermically without requiring atmospheric air, thus excluding nitrogen from the reformate stream. Alternatively, the reformer and SOFC are stationary at a base station and the PEM is aboard the vehicle. The SOFC and reformer have sufficient capacity to recharge hydrogen storage in the vehicle in a relatively short period of time, such as overnight.
