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