Abstract

PURPOSE:To obtain the titled alloy absorbing a large amount of hydrogen, easy to activate, and having a high reaction rate by substituting misch metal having a reduced Ce content for part of Ca in a Ca-Ni alloy and a metal such as Al for part of Ni so as to provide a spceified composition. CONSTITUTION:This hydrogenatable alloy is represented by a formula Ca1-x (CFMm)xNi5-yMy (where CFMm is misch metal having <=10wt% Ce content, M is Al, Mn, Cu, Fe, Co or Ti, 0<x<1, and 0<y<5). The alloy is a superior hydrogen storing alloy absorbing a large amount of hydrogen, easy to activate in the early stage of a hydrogenation reaction, and having a high reaction rate. The hysteresis between the absorption and dissociation of hydrogen is small, and the equilibrium hydrogen pressure at ordinary temp. is within the range in which the alloy is easily handled. It is desirable that (y) is 0.1-1.2 in the formula when (x) is 0.1-0.9.
