20080233462 | Hydrogen-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 |
20080286621 | Optimizing Hydrogen Generating Efficiency in Fuel Cell Cartridges - The present invention involves modifying certain characteristics of solid and aqueous chemical metal hydride fuels to increase the efficiency of hydrogen generation and/or to reduce the problems associated with such conventional hydride fuel sources. The present invention also relates to an apparatus ( | 11-20-2008 |

The receiver is adapted to receive the cartridge and to transport the first reactant to the reaction chamber after connection with the cartridge. The flow control device is adapted to stop the transport of reactant when the pressure in the reaction chamber reaches a predetermined pressure. | 09-09-2010 |
20110099904 | Gas 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 |
