<p>A hydrogen absorbing alloy having a crystal structure of CaCu5-type hexagonal system and represented by the general formula Re1-xYx(Ni5-yGy)z wherein Re is one of La, Ce, Nd, Pr, misch metal and lanthanum-rich misch metal, Y is yttrium, Ni is nickel, and G is an element capable of forming an intermetallic compound or complete solid solution in corporation with Ni or a mixture of such elements, and x, y and z are in the ranges of 0 < x </= 0.6, 0 < y </= 1 and 0.8 < z </= 1.2, respectively. This alloy has a high equilibrium hydrogen desorbing pressure at room temperature, a great capacity to absorb hydrogen and high durability to repeatedly absorb and desorb hydrogen.</p> |
