NOVELTY - The cartridge (10) comprises a case (20) defining an interior cavity, an igniter positioned within the cavity, a structural component positioned within the cavity, and an oxidizing agent positioned within the cavity. The structural component and case are formed of a particulate including a metallic material embedded in a matrix. The structural component is configured such that the metallic material and the oxidizing agent are configured to react together to generate hydrogen after the igniter generates sufficient heat to remove the matrix from the structural component.    USE - The cartridge is useful for the generation of hydrogen, which is useful as a source of energy in hydrogen consuming systems such as fuel cells, internal combustion engines, and portable power equipment and tools.    ADVANTAGE - The reusable or expendable cartridge rapid and economical generation of the hydrogen at constant temperature and pressure with low voltage of electricity, and minimizes the solid waste during the generation of the hydrogen.    DETAILED DESCRIPTION - The cartridge (10) comprises a case (20) defining an interior cavity, an igniter positioned within the cavity, a structural component positioned within the cavity, and an oxidizing agent positioned within the cavity. The structural component and case are formed of a particulate including a metallic material embedded in a matrix. The structural component is configured such that the metallic material and the oxidizing agent are configured to react together to generate hydrogen after the igniter generates sufficient heat to remove the matrix from the structural component for exposing sufficient metallic material to the oxidizing agent at a sufficiently high temperature and to initiate a chemical reaction between the metallic material and the oxidizing agent to generate hydrogen. The structural component is configured to generally maintain the position of the igniter relative to the case. The oxidizing agent is gelatinized water. An electrical element is positioned within the igniter, and is electrically connected with an exterior surface of the case. The igniter is configured to ignite when a voltage is applied to the electrical element.    DESCRIPTION OF DRAWING(S) - The diagram shows a perspective view of a cartridge.
