  • Patent number: 6686082
    Abstract: A fuel cell stack comprises fuel cell basic units, each of which including a gas diffuser/collector plate serving as an anode, an ion exchange membrane, disposed on top of the gas diffuser/collector plate and an air diffuser/collector plate serving as a cathode and disposed on top of the ion exchange membrane. The gas diffuser/collector has a face directed to the ion exchange membrane. This face is provided with a flow field incorporating a multiplicity of adjacent open-faced flow channels. Each open-faced flow channel has a cross-section continuously diminishing from its inlet to its outlet. The flow field, viewed from the top, forms a trapezoidal contour.

  • Publication number: 20020074888
    Abstract: The fuel cell powered electrical motor comprises an electrical motor and a plurality of fuel cell stacks. The electrical motor includes a shaft assembly, a stator encircling the shaft assembly, a rotor encircling the stator, a flywheel located perpendicularly to the shaft assembly, at a top part of the latter, and a base plate located perpendicularly to the shaft assembly, at a low part of the latter. Base plate is designed to allow a fuel from an outside source to enter and exit the several fuel cell stacks and is also adapted for the passage of electrical power output from the fuel cell stacks to an external controller and from the latter to the stator and rotor.
