Abstract
Vehicle engine exhaust is sent to a reformer, which produces hydrogen from fuel remaining in the exhaust. The hydrogen is stored in a hydrogen tank, and is used by a fuel cell to produce electricity to recharge the vehicle battery and/or to supply propulsion current to an electric propulsion system to propel the vehicle in lieu of using the engine.
