  • Publication number: 20110104021
    Abstract: The present application is directed to a hydrophobic membrane assembly (28) used within a gas-generating apparatus.

  • Publication number: 20110099904
    Abstract: The present application is directed to gas generators comprising a fuel mixture and a catalyst. The catalyst is contained in a self-regulated reactor or buoy, and selectively opens and closes to produce a gas in accordance with the demand for gas. This fuel mixture is generally a solution formed by dissolving a solid fuel component in a liquid fuel component. The mixing preferably occurs before the first use, and more preferably occurs immediately prior to the first use. The inventive gas generators preferably further comprises a starting mechanism that isolates the solid fuel from the liquid fuel or vice versa before the first use. In one embodiment, the starting mechanism further comprises a catalyst shield mechanism that isolates the catalyst in the reactor or buoy from the liquid and/or the solid fuel prior to the first use.

  • Patent number: 7896934
    Abstract: A gas-generating apparatus (10) includes a reaction chamber (18) containing a solid fuel component (24) and a liquid fuel component (22) that is introduced into the reaction chamber by a fluid path, such as a tube, nozzle, or valve. The flow of the liquid fuel to the solid fuel is self-regulated. Other embodiments of the gas-generating apparatus are also disclosed.

  • Patent number: 7779856
    Abstract: A fuel supply connectable to a fuel cell is disclosed. The fuel supply comprises an outer casing and a fuel liner and an effective amount of fuel in the space between the outer casing and the fuel liner to control the pressure inside the fuel liner. In one example, the fuel inside the fuel liner is methanol, and the fuel between the outer casing and the fuel liner is methanol or methanol gel.

  • Publication number: 20100104481
    Abstract: Disclosed herein are multiple embodiments of a hydrogen generator (10) that measures, transports or stores a single dose of a viscous fuel component from first fuel chamber (12) in storage area (38) when the internal hydrogen pressure (44, 44?) of the hydrogen generator is high, and transports this single dose to a metal hydride fuel component in second fuel chamber (14) when the internal pressure is low, so that the viscous liquid and metal hydride fuel components react together to generate more hydrogen and to restart the cycle. The viscous fuel component can be water or alcohol, such as methanol, in liquid or gel form, and the metal hydride fuel component can be sodium borohydride or other metal hydride that chemically reacts with the viscous fuel to produce hydrogen. The metal hydride fuel component can be in solid or viscous form, e.g., aqueous form.

  • Publication number: 20080233457
    Abstract: Disclosed herein are connecting valves with an interchangeability feature (18, 20) to ensure that the fuel cell fuel matches the fuel cell. Also disclosed are retainer mechanisms (28, 30, 32, 36) capable of releasably connecting the fuel supply to the fuel cell or to the electronic device equipped with a fuel cell. An improvement to the connecting valves to decrease the amount of residual fuel left in the fuel supply is also provided.

  • Publication number: 20080233462
    Abstract: The present application is directed to a gas-generating apparatus and various pressure regulators or pressure-regulating valves. Hydrogen is generated within the gas-generating apparatus and is transported to a fuel cell. The transportation of a first fuel component to a second fuel component to generate of hydrogen occurs automatically depending on the pressure of a reaction chamber within the gas-generating apparatus. The pressure regulators and flow orifices are provided to regulate the hydrogen pressure and to minimize the fluctuation in pressure of the hydrogen received by the fuel cell. Connecting valves to connect the gas-generating apparatus to the fuel cell are also provided.

  • Publication number: 20080206113
    Abstract: A gas-generating apparatus (12) includes a fuel introducing system that has a fuel transporting system that is pressure regulated and indexed. A reaction chamber (18) having a fluid fuel component (22) and an indexing mechanism (24) operatively connected to a solid fuel component are provided. The solid fuel component of the present invention is introduced into the fluid fuel component within the reaction chamber. Further, the indexing mechanism includes a ratcheting mechanism that may be in direct contact with the fluid fuel component. Alternatively, the reaction chamber may be contained within a pod which also contains the reservoir containing the fluid fuel component, a plurality of which are provided. The indexing mechanism advances the pods sequentially so that the fuel components may be introduced. Other indexing mechanisms are provided. A secondary fuel cell (14?) may be provided to extract excess production from the reaction chamber.

  • Publication number: 20080199759
    Abstract: A fuel supply (10) is attachable to a fuel cell system (12). The fuel supply includes a fuel supply connector (14) configured to be attached to the fuel cell system. A fuel supply connector automatically separates the fuel supply from the fuel cell system in a predetermined manner if exposed to a separation load. Valves (24, 26) or filler material (23a-d) are used to automatically stop the flow of fuel through the fuel supply connector. Alternatively, the fuel supply connector includes a flexible tube (114) and a valve disposed within the connector. The flexibility of the tube prevents the connector from breaking in case of a separation load.
