Members of a preferred class of compounds, represented by the empirical formula CeNi.sub.5-x Mn.sub.x wherein 'x' has a value between 0.1 and about 1.0. These alloys react with hydrogen readily and can absorb a large amount of hydrogen at moderate pressure and temperature and are particularly suitable for use as hydrogen storage materials.
