NOVELTY - The hydrogen storing-releasing material has a porous support and at least one hydrogen storage compound applied on the surface of the porous support. The porous support has high surface area of greater than or equal to 50 m2/g. The hydrogen storage compound stores and releases bulk quantities of hydrogen at higher rate and at lower temperature. The storage and releasing amount of the hydrogen storage compound is less when it is not applied to the porous support.    USE - Hydrogen storing-releasing material is used for hydrogen storing devices (claimed). Uses of the hydrogen storing-releasing material include but are not limited to on-board devices, off-board devices, hydrogen generators, fuel sources, solid oxide fuel cells, automobile engines, combustion engines and vehicle engines.    ADVANTAGE - The hydrogen storing-releasing material effectively stores and releases hydrogen at higher rates, minimizes unwanted side reaction, prevents contamination of products and provides hydrogen with high purity.    DETAILED DESCRIPTION - The hydrogen storing-releasing material has a porous support and at least one hydrogen storage compound applied on the surface of the porous support. The porous support has high surface area of greater than or equal to 50 m2/g. The hydrogen storage compound stores and releases bulk quantities of hydrogen at higher rate and at lower temperature. The storage and releasing amount of the hydrogen storage compound is less when it is not applied to the porous support. The hydrogen storage compound is selected from lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, sodium, magnesium, aluminum, silicon and/or phosphorus. The high surface area porous material is selected from interconnected porous material, non-interconnected porous material, channeled porous material, porous silica, mesoporous silica, porous titanium dioxide, mesoporous titanium dioxide, porous carbon, mesoporous carbon, porous zeolites, porous aerogels and/or porous polymers. The hydrogen storage compound is further selected from hydrides, metal hydrides, conducting polymers and nitrogen-boron compounds. The hydrogen storage-releasing material further contains a catalyst. The catalyst is a transition metal catalyst. The porous support has porosity of at least 20 volume%. An INDEPENDENT CLAIM is included for manufacture of hydrogen storing-releasing material.
