  • Inertial pump for moving gases in a micro fuel cell
    Patent number: 7732085
    Abstract: A fuel cell device includes at least one and preferably two gas storage chambers, the gas storage chambers being connected via gas flow channels to a fuel cell membrane, such as a proton exchange membrane. A piston in each gas storage chamber moves to compress the gas upon being subject to an acceleration force. A flow control opens upon a predetermined condition being achieved to provide the compressed gases to a fuel cell membrane.

  • Polymer electrolyte membrane fuel cell stack
    Patent number: 7534514
    Abstract: A fuel cell includes a stack of electrolyte membranes joined to one another to form an interior space and an exterior space. Fuel, such as hydrogen, is provided to the interior space. The electrolyte membranes are circular and joined to adjacent membranes at the outer perimeters to enclose the interior space. A stack of such membrane assemblies is provided on a shaft and is rotated within a housing to drive off byproduct water. The water is collected and recirculated by spraying over the fuel cell stack for cooling and hydration.
