  • Fuel cell engine having a propulsion motor operatively connected to drive a fluid supply device
    Patent number: 6223844
    Abstract: A fuel cell engine for a vehicle comprises at least one fuel cell stack for producing electric power from a fuel and an oxidant, a propulsion motor, for propelling the vehicle. The propulsion motor is connected to receive electric power from the at least one fuel cell stack and is operatively connected to mechanically drive a device for directing a fluid stream into the fuel cell stack. In preferred embodiments the propulsion motor is operatively connected to drive a device for directing at least one reactant fluid stream into the fuel cell stack.
