NOVELTY - A composite material for hydrogen gas generation from water in an exothermic reaction, is a powder form of a metal and sodium oxide or sodium hydroxide. The composite material powder is exposed to an acidic gas allowing the alkali component of the composite material powder to be coated with a layer of salt, which salt is inert to aluminum and soluble in water, and once the composite material is exposed to water and the soluble layer of salt is dissolved, the exothermic reaction between the composite material and the water allows for the generation of low pressure hydrogen gas.    USE - As composite material for hydrogen gas generation from water in an exothermic reaction; useful in a hydrogen generator unit (claimed) used in hydrogen fuelling systems for fuel cells and internal combustion engine standalone energy system. The hydrogen generated is utilized to various applications such as for vehicle propulsion, for fuel for micro energy system (battery replacements), and for emergency power supply systems.    ADVANTAGE - The composite material is improved composite material for generation of hydrogen gas on demand; is more reliable and user friendly composite material and finally environment friendly as it provides disposal of any residue product after the hydrogen gas generation. The composite material powder is exposed to an acidic gas allowing the alkali component of the composite material powder to be coated with a layer of salt, which salt is inert to aluminum and soluble in water, and once the composite material is exposed to water and the soluble layer of salt is dissolved, the exothermic reaction between the composite material and the water allows for the generation of low pressure hydrogen gas. The benefit of the stabilization of the composite powder makes it much more user friendly and not so reactive with water moisture or water. Transportation and storage of the composite material can be costly as it needs to be done in a controlled environment where there is no risk of any water getting in contact with the composite powder material. The use and handling of the composite material is made much more convenient and safe. The manufacturing approach of spray forming and the stabilization process allows for a very cost efficient and user friendly end product for future transportation and use by end users. The advantage of the process for manufacturing composite is that it does not require any specialist machinery and can be performed using equipment that is readily available. The use of hydrogen system can substantially reduce the cost of a vehicle utilizing battery packs.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a hydrogen generator unit for generating low-pressure hydrogen from water, comprising at least one reaction chamber to employ an extracting chemical process to generate low-pressure hydrogen from an exothermic reaction between a composite material and water, where the composite material has a water soluble salt layer which needs to dissolve prior to the exothermic hydrogen gas generating reaction is initiated; and    (2) manufacturing a composite material, involving: melting a metal and injecting the molten metal stream into an atomization chamber; injecting at least one inert gas at higher pressure to create metal droplets and control the environment in the chamber to avoid ignition; spraying the molten metal droplets onto a cooling plate where condensation and cooling takes place; collecting the meal in powdered form post the cooling plate; mixing the powdered metal with sodium hydroxide to generate a blended material; and exposing the blended material to an acidic gas allowing a thin layer of a water soluble salt to form on the blended material and forming a stabilized composite material.    DESCRIPTION OF DRAWING(S) - The figure shows a flow diagram of the process for manufacturing a composite material.
