Abstract
Hydrogen storage alloy has: (1) a main composition expressed by the formula of Mm−(Ni−Al−Co−Mn−Cu); (2) a ratio of the number of atoms expressed by the formula (Ni−Al−Co−Mn−Cu) is 5.5<(Ni+Al+Co+Mn+Cu)≦7.0, and 4.0≦Ni, when Mm is set at 1 in a ratio of the number of atoms; and (3) an internal structure having hydrogen storage alloy phase expressed by the general formula of ABand a second phase existing in the hydrogen storage alloy phase, wherein the whole the composition is expressed by the formula of MmiNiAlCoMn, and 0.3<(p+q+r+s+t)≦1.8.
