  • Fuel Cell Hybrid-Electric Heavy-Duty Vehicle Drive System and Method
    Publication number: 20080277175
    Abstract: A system and a method that provides fuel cell and energy storage hybrid-electric propulsion and control for a heavy-duty vehicle over 10,000 pounds GVWR. Power output is supplied from a fuel cell system to a high-power intermediate DC bus through a fuel cell DC/DC converter. Power output is supplied from an energy storage system to the high-power intermediate DC bus through a separate energy storage fuel cell DC/DC converter. The received power is combined on the high-power intermediate DC bus to create a stable voltage. The stable voltage from the high-power intermediate DC bus is supplied to one or more electric motors/generators to accelerate the heavy duty vehicle.
