Abstract: A hydrogen generator and a fuel cell system including the hydrogen generator are disclosed. The hydrogen generator includes a fuel composition including a hydrogen containing material that releases hydrogen gas to produce hydrogen when heated. A biasing member working in cooperation with a heating element and retainer, all of which are disposed within a unitary container, facilitate and control the release of hydrogen gas. The fuel composition can be segregated into individual quantities.

Abstract: A hydrogen generator is provided for generating hydrogen gas for a fuel cell stack. The hydrogen generator includes a reaction area and a reactant storage area for storing a reactant composition for reacting to generate hydrogen gas. The hydrogen generator also includes a high pH solution contained within a solution storage area. Hydrogen gas is discharged through an outlet that passes through a filter to supply gas to the fuel cell. A predetermined quantity of high pH solution is injected into the reaction area to stop the reaction when electrical power is no longer demanded.

Abstract: An electrochemical cell is provided having a first electrode, such as a cathode, and a plurality of second electrodes, such as anodes, provided in a cell container. A plurality of cavities are formed within the cathode. A separator and anode are disposed within each of said cavities, and a current collector electrically connects the anodes together. According to one embodiment, a plurality of cylindrical anodes are provided. According to a second embodiment, a plurality of semi-cylindrical anodes are disclosed.
