Hydrogen Storage Properties of the Composite Material Mg-ZrTiMn by Reactive Mechanical Milling in a Hydrogen Atmosphere In recent years substitutive energies for fossil fuels are strongly demanded. The hydrogen is one of the promising materials. However, the hydrogen has a serious problem in the transportation and the storage. A compression method, a liquefaction method and an absorption method are nominated for techniques to solve the problem. We paid our attention to a metallic alloyed material for hydrogen storage by the absorption method. The reason is why the material for hydrogen storage can generally contract a volume of the hydrogen to 1/1,000. On the other hand, the material has same defects, i.e., it is heavy in weight, and it's absorbing/desorbing temperature and rate levels are high and late, respectively. We have been trying to improve these defects by adopting composite materials of Mg-ZrTiMn, paying attention for Mg to absorb much hydrogen per weight and for ZrTiMn alloy to absorb/desorb within low temperature level.
