  • Apparatus for refueling a direct oxidation fuel cell
    Patent number: 7128106
    Abstract: A refueling arrangement for a direct oxidation fuel cell. A refueling cartridge includes a coupling which is geometrically keyed to a fueling port associated with the fuel cell. By properly engaging the coupling with the fueling port, a fuel flow path is opened which allows fuel to pass from the cartridge to the fuel cell. Disengaging the coupling from the fueling port closes the fuel flow path. Refueling is accomplished in rapid, trouble-free and safe manner.
