    Abstract: A hydrogen generator and a method of producing hydrogen gas using stabilized aluminum hydroxide and water are disclosed. The hydrogen generator contains stabilized aluminum hydride, water, a base, and a reaction chamber within which at least a portion of the stabilized aluminum hydride reacts with at least a portion of the water to produce hydrogen gas. The water that reacts with the stabilized aluminum hydride is contained in a basic aqueous solution including at least a portion of the base. The base can be included with the water in the basic aqueous solution, stored in a reservoir separate from the stabilized aluminum hydroxide, or the base can be a solid contained in a mixture with the stabilized aluminum hydroxide and mix with water when added to the mixture to form the basic aqueous solution.

    Abstract: Disclosed are a hydrogen generator and a method of producing hydrogen gas therefrom. A fuel unit containing a fuel that releases hydrogen gas when heated is removably disposed in a cavity within a housing having a door. A heater assembly for heating the fuel unit is disposed in the hydrogen generator. A mechanism retracts the heater assembly from the fuel unit when the door is opened and extends the heater assembly to contact the fuel unit when the door is closed. When the heater assembly is retracted, more space is available into which the fuel unit can be inserted to prevent damage to the heater assembly and the fuel unit, and when the heater assembly is extended, good contact is provided between the heater assembly and the fuel unit for efficient heating. A cam bar can move the heater assembly normal to the lateral motion of the cam bar.
