<p><P>PROBLEM TO BE SOLVED: To provide a hydrogen storage material capable of storing and releasing hydrogen reversibly at low temperatures without lowering the amount of available hydrogen, its manufacturing method and a hydride compound material. <P>SOLUTION: The manufacturing method comprises a blending process of blending NaH with Al containing 0.05-2.0 mass% of Fe and a crushing/mixing process of crushing and mixing the resultant blend in a non-oxidative atmosphere, and the Fe-containing compound particles are crushed to particle sizes below 10 nm in the crushing/mixing process. The hydrogen storage material consists of a matrix comprising NaH, Al and NaAlH<SB>4</SB>and Fe-containing compound particles dispersed in the matrix, with the particle sizes of the compound particles below 10 nm. A hydride compound material obtained by causing the hydrogen storage material to absorb hydrogen is also provided. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
