  • Patent number: 9660279
    Abstract: Disclosed are a fuel unit for a hydrogen generator and methods for producing the fuel unit and the hydrogen generator. A fuel sheet (50) is made by disposing a plurality of fuel pellets (50A-50J) containing a hydrogen-containing material on a substrate (52), and one or more fuel sheets are formed into a non-cylindrical fuel sheet assembly my moving (e.g., bending) a portion of the fuel sheet (50) to position pellets adjacent to each other such that adjacent sides of the adjacent pellets lie in essentially parallel planes. A non-cylindrical fuel unit is produced from one or more of the fuel sheet assemblies. Fuel units can be replaceably disposed in a hydrogen generator, and fuel pellets can be selectively heated to produce hydrogen gas as needed.

  • Publication number: 20150064104
    Abstract: Disclosed is a hydrogen generator that produces hydrogen by thermal decomposition. An electric circuit including a plurality of parallel branches, each including at least one electric heating element, is arranged in a sequence. The circuit also includes a normally open switch between adjacent branches and a normally closed switch in each branch but the last to provide current to the heating elements in the sequence of the parallel branches. Each heating element provides heat to thermally decompose a portion of a reactant, open the normally closed switch in the same branch, and close the normally open switch following that branch, energizing and deenergizing the heating elements in sequence. Each of the normally open switches includes a switch material with a resistivity that permanently decreases to close the switch in response to heating, and each of the normally closed switches opens in response to heating.
