Patent application numberDescriptionPublished
20080199759Separable Fuel Cartridge - A fuel supply (08-21-2008
20080206113Hydrogen Generating Fuel Cell Cartridges - A gas-generating apparatus (08-28-2008
20080216906Hydrogen Generating Fuel Cell Cartridges - A gas-generating apparatus (09-11-2008
20080233457Fuel Supply with Improved Connecting Valve - Disclosed herein are connecting valves with an interchangeability feature (09-25-2008
20080233462Hydrogen-Generating Fuel Cell Cartridges - 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.09-25-2008
20090123342Fuels for Hydrogen Generating Cartridges - The present invention increases the amount of hydrogen produced or released from reactions between a metal hydride fuel and liquid reactant. The present invention also decreases the volume of a hydrogen generating cartridge by reducing the pH of the liquid reactant.05-14-2009
20100104481Hydrogen Gas Generators - Disclosed herein are multiple embodiments of a hydrogen generator (04-29-2010
20110099904Gas Generator with Starter Mechanism and Catalyst Shield - 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.05-05-2011
20110104021Hydrogen Membrane Separator - The present application is directed to a hydrophobic membrane assembly (05-05-2011
20110120008Hydrogen Generating Fuel Cell Cartridges - A gas-generating apparatus (05-26-2011
