<P>PROBLEM TO BE SOLVED: To provide an Mg based hydrogen storage material, for solving the problem that the hydrogen storage material is expected as an application to fuel storage for a fuel fuel, but, its hydrogen storage/discharge rates are low and hydrogen storage/discharge temperatures are also high, thus its practical use therefor has been difficult, having practical hydrogen storage/discharge temperature, practical hydrogen storage/discharge rates and discharge pressure equal to or above the atmospheric pressure. <P>SOLUTION: The Mg based hydrogen storage material contains Mg and carbon, or Mg, carbon and Ni. At the time when carbon is added to Mg, the hydrogen storage/discharge quantity within practical time increases compared with the case of only Mg, and further, hydrogen dissociation pressure also lowers compacted with the case of only Mg. Further, Ni is added, thereby lowering the hydrogen discharge temperature. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
