  • FUEL CELL FEED SYSTEMS
    Publication number: 20140127610
    Abstract: Fuel feed systems capable of providing substantially consistent flow of fuel to a fuel cell and also capable of tolerating varying pressures from a reservoir (also referred to as fuel supply or fuel cell cartridge) and the fuel cell while maintaining substantially consistent control flow to the fuel cell are disclosed.

  • MANAGING GAS BUBBLES IN A LIQUID FLOW SYSTEM
    Publication number: 20100124676
    Abstract: A system and method for managing gas bubbles in a liquid flow system are described. In particular, according to the system and method, novel techniques reduce a volume of cavities in the liquid flow system and limit a cross-sectional area of the liquid flow system to a maximum cross-sectional area of tolerably sized bubbles. In this manner, by reducing the cavity volumes and limiting cross-sectional areas, the formation of intolerably sized bubbles and the aggregation of tolerably sized bubbles into intolerably sized bubbles are each substantially prevented. Also, bubbles may be removed from the system to reduce the quantity of bubbles that are to be managed.

  • SYSTEM TO RESERVOIR CONNECTOR
    Publication number: 20100124689
    Abstract: A system-to-reservoir connector is disclosed in which a system-side-sub-connector and a reservoir-side-sub-connector provide for a fluid connection that is resilient to external forces, is substantially leak-proof upon insertion and retraction, and is orientation independent.
