| 20140044605 | Fuel Unit, Refillable Hydrogen Generator And Fuel Cell System - A packaged fuel unit and a refillable hydrogen generator that uses the fuel unit to produce hydrogen gas are disclosed. The fuel unit includes a reactant that can undergo a thermal decomposition reaction that produces hydrogen gas when heated to at least a minimum initiation temperature. The reactant is contained within a package that includes a poor thermal conductor with one or more thermal conductor sections for conducting heat from outside the package to the reactant. The hydrogen generator includes a holder with a cavity in which the fuel unit can be removably disposed and a heating system for heating the fuel unit when disposed therein. The hydrogen generator can be part of a fuel cell system including a fuel cell battery that is provided with hydrogen gas from the hydrogen generator. | 02-13-2014 |
| 20140295304 | METHODS OF GENERATING HYDROGEN GAS AND POWER - A hydrogen generator and a fuel cell system including a fuel cell battery and the hydrogen generator. The hydrogen generator includes a cartridge, a housing with a cavity to removably contain the cartridge, and an initiation system. The cartridge includes a casing; a plurality of pellets including a hydrogen containing material; a plurality of solid heat transfer members in contact with but not penetrating the casing; a hydrogen outlet in the casing; and a hydrogen flow path from each pellet to the hydrogen outlet. A plurality of heating elements is disposed inside the housing. When the cartridge is in the cavity, each heating element is disposed so heat can be conducted from the heating element and through the casing and corresponding heat transfer member to initiate the release of hydrogen gas. The initiation system can selectively heat one or more pellets to release hydrogen gas as needed. | 10-02-2014 |

| 20150072256 | REFILLABEL HYDROGEN GENERATOR - A hydrogen generator and a fuel cell system including the hydrogen generator are disclosed. The hydrogen generator includes a reactant that undergoes a thermal decomposition reaction to produce hydrogen when heated. A laser is used to initiate the reaction. The reactant is contained in a reactant composition in a user-replaceable disc-shaped fuel unit. The reactant composition can be segregated into individual quantities. The fuel unit and the laser beam are periodically realigned by incrementally rotating the fuel unit and/or incrementally redirect the laser beam. | 03-12-2015 |
| 20150089796 | METHOD OF MAKING A PACKAGED FUEL UNIT FOR A HYDROGEN GENERATOR - A method of making a package for a fuel unit, a fuel unit including the package, and a hydrogen generator including one or more of the fuel units are disclosed. The package includes a package strip made by forming apertures in a nonconductive substrate strip, forming conductor sections in a conductor strip, aligning the substrate and conductor strips, bonding the conductor sections to the substrate strip to cover the apertures, and removing non-bonded portions of the conductor strip. A package enclosing a hydrogen generating reactant is formed by securing a segment of the package strip to itself, to one or more other segments and/or to one or more other package components. One or more conductor sections in the package strip are in thermal contact with one or more quantities of reactant composition so heat can be transferred thermally decompose the reactant composition and generate hydrogen gas. | 04-02-2015 |
| 20150182938 | HYDROGEN GAS GENERATOR - A hydrogen generator, a fuel cell for use in the hydrogen generator and a fuel cell system are disclosed. The hydrogen generator includes a housing and a plurality of fuel pellets disposed in the housing. Each fuel pellet includes a hydrogen-containing reactant that will react to release hydrogen gas when heated. The hydrogen generator also includes a plurality of heating elements extending into the plurality of fuel pellets to generate heat to selectively heat one or more fuel pellets to initiate a reaction to produce hydrogen gas. The hydrogen generator further includes a plurality of electrical contacts operatively coupled to the plurality of heating elements to selectively supply electrical power to the plurality of heating elements. | 07-02-2015 |
| 20150203353 | FUEL UNIT, GAS GENERATOR AND SYSTEM - Disclosed is a fuel unit for a gas generator such as a hydrogen gas generator that can supply gas to a gas consuming system such as a fuel cell system. The fuel unit includes a housing containing a solid fuel composition and a heat producing material. The fuel composition contains gas releasing solid material that reacts to release gas when heated. The heat producing material reacts exothermically to produce heat. A plurality of quantities of the heat producing material are in thermal communication with corresponding portions of an unsegregated quantity the fuel composition such that, following initiation of a reaction of each quantity of the heat producing material, the quantity of heat producing material will heat the corresponding portion of the unsegregated quantity of the fuel composition, and the corresponding portion of the unsegregated quantity of the fuel composition will react to release a quantity of the gas. | 07-23-2015 |
