  • Mobile hydrogen dispenser for fuel cell vehicles
    Patent number: 10920934
    Abstract: A mobile dispenser may be used to at least partially fill hydrogen tanks of fuel cell-powered vehicles. The dispenser uses a purely mechanical control of the fill using an orifice plate across which a pressure differential is maintained through use of a backpressure regulator whose reference pressure is controlled by a differential pressure regulator. Because it does need or use electrical power, it may be used in situations where no electrical power is available or convenient.
    Type: Grant

    Assignee: Air Liquide Advanced Technologies U.S. LLC
