NOVELTY - Hydrogen generator comprises: a cartridge (100) comprising a casing, many solid pellets (120) stacked within the casing, and a hydrogen outlet valve (110) in the casing; a compartment comprising a housing, a hydrogen outlet through the housing, and a cavity within the housing; and an induction heating system comprising many electrically conductive secondary coils (124) within the cartridge casing with each secondary coil in contact with at least one of the pellets, and at least electrically conductive one primary coil (220) within the compartment housing.    USE - The hydrogen generator is useful in a fuel cell system (claimed) that produces electricity for an electronic device, and for providing hydrogen gas which is used by a hydrogen consuming system (i.e. fuel cell system).    ADVANTAGE - The hydrogen generator: uses no liquid reactants; utilizes the cartridge which includes no catalyst (claimed); is inexpensive, easy to manufacture, and safe to store and use; exhibits good energy efficiency; is able to produce a large total volume of hydrogen gas per unit of mass and per unit of volume of the hydrogen generator, able to control the supply of hydrogen on an as needed basis, able to quickly start and stop producing hydrogen, and able to operate at or below a desired maximum temperature; in the fuel cell system can be replaced after hydrogen containing materials have been consumed; and is durable and reliable for a long period of time.    DETAILED DESCRIPTION - Hydrogen generator comprises: a cartridge (100) comprising a casing, many solid pellets (120) stacked within the casing (where each pellet comprises at least one hydrogen containing material capable of releasing hydrogen gas when heated), and a hydrogen outlet valve (110) in the casing; a compartment comprising a housing, a hydrogen outlet through the housing, and a cavity within the housing within which the cartridge can be removably disposed; and an induction heating system comprising many electrically conductive secondary coils (124) within the cartridge casing with each secondary coil in contact with at least one of the pellets, and at least electrically conductive one primary coil (220) within the compartment housing, where the induction heating system is configured to receive an electric current from a power source, provide an electromagnetic field from a flow of the current in the at least one primary coil, induce an electric current in the at least one secondary coil, and provide heat from a flow of the induced electric current, thus heating the pellets. An INDEPENDENT CLAIM is also included for a fuel cell system comprising a fuel cell battery, and the hydrogen generator.
