NOVELTY - The apparatus for storing and delivering hydrogen comprises a storage component. The storage component comprises a hydrogen storage medium. The hydrogen storage medium comprises an aluminoborane hydride (1).    USE - Apparatus used for storing and delivering hydrogen e.g. fuel cell system and combustion engine of vehicles.    ADVANTAGE - The apparatus safely and efficiently stores hydrogen.    DETAILED DESCRIPTION - The apparatus for storing and delivering hydrogen comprises a storage component. The storage component comprises a hydrogen storage medium. The hydrogen storage medium comprises an aluminoborane hydride of formula (1): AlBxHn, where x is 4 or more and n is 10 or more. The aluminoborane hydride is selected from AlB4H11, AlB5H12, AlB5H16, AlB6H13, AlB7H20 and/or AlB9H24. The hydrogen storage medium comprises at least one catalyst (0.1-10 mole%). The catalyst is selected from hydrides, fluorides, chlorides, oxides, elements and/or alloy. The hydride catalyst is selected from lithium hydride, sodium hydride, magnesium hydride, potassium hydride, calcium hydride, lithium aluminum hydride, sodium aluminum hydride, magnesium aluminum hydride, potassium aluminum hydride, calcium aluminum hydride, titanium hydride and/or vanadium hydride. The fluoride catalyst and chloride catalyst are selected from fluorides and chlorides of lithium, sodium, magnesium, potassium, calcium and/or transition metals such as titanium, ferrous, ferric, copper, ruthenium, rhodium and/or zirconium. An oxide catalyst is selected from aluminum oxide, silicon dioxide, niobium pentoxide, stannous oxide and/or transition metal oxides. The element and alloy catalysts are selected from carbon, transition metals, its alloys and borides such as palladium, platinum, rhodium, ruthenium, lanthanum, nickel, carbon, iron, cobalt, copper, titanium, rhenium, lanthanum pentanickel (LaNi5), iron-titanium (FeTi), nickel boron (NiB) and/or nickel boride (NiB2). The aluminoborane hydride further contains a dopant (0-20 mole%) instead of aluminum. The dopant is selected from titanium, vanadium, chromium, zirconium, niobium, yttrium, lanthanum, manganese, nickel, iron, cobalt, silicon, copper and/or zinc.
