TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The hydride reactant comprises sodium borohydride and water-soluble anhydrous activating agent (20-60 wt.%).Preferred Components: The activating agent comprises salt(s) of alkaline earth metal, alkali metal, or halide, preferably beryllium fluoride, beryllium chloride, beryllium bromide, beryllium iodide, magnesium fluoride, magnesium bromide, magnesium chloride, magnesium iodide, calcium fluoride, calcium chloride, calcium bromide, calcium iodide, lithium fluoride, lithium chloride, lithium bromide, lithium iodide, sodium fluoride, sodium chloride, sodium bromide, sodium iodide, potassium fluoride, potassium chloride, potassium bromide, potassium dioxide, lithium chloride, lithium sulfide, lithium selenide or cupric chloride. The activating agent may be cobalt, platinum, palladium, iron, manganese, chromium, or preferably copper, ruthenium or nickel. The hydride reactant is lithium aluminum hydride. Acid and water are mixed prior to being injected from the distribution aperture.    TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Parameters: The reaction parameter includes hydrogen pressure within the cartridge and temperature of the cartridge. The amount of liquid reactant exiting a distribution aperture does not exceed 50 mul per injection cycle and the cartridge temperature does not exceed 80degreesC.Preferred Components: Liquid distribution apertures are formed along the liquid conduit. Each liquid conduit has a separate control valve and is surrounded by a fabric sleeve. The liquid conduits are spaced radially from a center point in a non-uniform configuration. The control system activates a cooling system based on the cartridge temperature. The hydride is enclosed in a fabric pouch having a greater area than thickness. The pouch is divided into sections. The hydrogen generation system includes an acid reservoir, a water reservoir, and a sealing device positioned between the ports of cartridge and the cartridge receiver, and a holding assembly for bringing the cartridge and cartridge receiver together with sufficient force to form an effective seal.Preferred Dimensions: The liquid distribution apertures have a diameter of 50-1,000 microns.
