NOVELTY - Electrode material composition comprises at least one transition metal, at least one high electron mobility component, and a source of ionizing radiation.    USE - The composition is used as electrode materials in devices, e.g. battery, capacitor, and fuels cells (claimed). It can also be used to generate hydrogen and oxygen gas. It is useful as electrode material in a hybrid fuel cell device. It can also serve as both electrode material and fuel source. The hydrogen gas may be used in internal combustion engines, heating, ion propulsion, magnetohydrodynamics (MHD), fuel cells, welding, hydrogenation of oils, hydrogenation of petroleum and petrochemical fuels, hydrogenation of polymer related materials, reduction of organic compounds, reduction of inorganic and organometallic compounds, hydrogenation of volatile materials in vapor deposition processes, conventional jet propulsion, and rocket fuel.    ADVANTAGE - The novel composition avoids the need to provide hydrogen fuel separately, and allows the use of the fuel cell electrolyte as an electron transport medium, thus the fuel cell has a greater energy density and more potential applications than available with conventional fuel cell systems. It is less expensive than the platinum or platinum alloy electrodes of conventional hydrogen fuel cells.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for;    (1) A method of producing hydrogen gas, by contacting the above composition with water or aqueous hydroxide ion;    (2) A method of manufacturing the above composition, by providing at least one transition metal, at least one electron mobility component, and a source of ionizing radiation as ingredients, melting to form a mixture; and cooling until the mixture solidifies;    (3) A battery comprising an anode comprising the above composition, a cathode, and an electrolyte;    (4) A capacitor comprising an anode in contact with a sample of carbon foam and comprising the above composition, a cathode, an electrolyte, and a dielectric; and    (5) A fuel cell assembly comprising a conventional hydrogen fuel cell and a hydrogen generator comprising the above composition.
