ABSTRACT:
The present invention provides a hydrogen absorbing alloy containing a phase of a Pr5Co19type crystal structure having a composition defined by a general formula A(4−w)B(1+w)C19(A denotes one or more element(s) selected from rare earth elements including Y (yttrium); B denotes an Mg element; C denotes one or more element(s) selected from a group consisting of Ni, Co, Mn, and Al; and w denotes a numeral in a range from −0.1 to 0.8) and having a composition as a whole defined by a general formula R1xR2yR3z(15.8≦x≦17.8, 3.4≦y≦5.0, 78.8≦z≦79.6, and x+y+z=100; R1 denotes one or more element(s) selected from rare earth elements including Y (yttrium); R2 denotes an Mg element, R3 denotes one or more element(s) selected from a group consisting of Ni, Co, Mn, and Al; the numeral of Mn+Al in the z is 0.5 or higher; and the numeral of Al in the z is 4.1 or lower).
