    Abstract: The invention relates to micro fuel cell systems whose performance is enhanced by an accurate fluid delivery system. The fluid delivery system improves reactant fluid provision to meet electrical output, while maintaining correct stoichiometries for chemical processing in a downstream reactor. The fluid delivery system includes a pressure source and a differential flow meter. The differential flow meter uses a flow restrictor and a sensor. The pressure source moves a fluid through the flow restrictor; the sensor detects differential pressure in the flow restrictor and outputs a signal that permits dynamic control of fluid flow, e.g., by controlling a pump.

    Abstract: The present invention relates to fuel cells and components used within a fuel cell. Heat transfer appendages are described that improve fuel cell thermal management. Each heat transfer appendage is arranged on an external portion of a bi-polar plate and permits conductive heat transfer between inner portions of the bi-polar plate and outer portions of the bi-polar plate proximate to the appendage. The heat transfer appendage may be used for heating or cooling inner portions of a fuel cell stack. Improved thermal management provided by cooling the heat transfer appendages also permits new channel field designs that distribute the reactant gases to a membrane electrode assembly. Flow buffers are described that improve delivery of reactant gases and removal of reaction products. Single plate bi-polar plates may also include staggered channel designs that reduce the thickness of the single plate.

    Abstract: The invention relates to a compact and portable fuel cell package. The package includes a fuel cell that generates electrical energy. Some packages also include a fuel processor that produces hydrogen from a fuel source. Fuel cell packages described herein provide power densities (power per unit volume or mass) at levels not yet seen. One package employs an interconnect disposed at least partially between a fuel cell and a fuel processor. The interconnect forms a structural and plumbing intermediary between the two. Given the portable size of fuel cell packages described herein, the invention is well suited to power portable electronics devices. One portable fuel cell package includes a tether, which allows electrical and detachable coupling to an electronics device.
