Abstract

PURPOSE:To obtain a hydrogen storing material easy to activate and having a high rate of hydrogenation by dispersing the oxide of one or more among Sc, Y, lanthanides and actinides in an intermetallic Fe-Ti compound. CONSTITUTION:This hydrogen storing metallic material capable of reversibly absorbing hydrogen is represented by a formula (Fe1-xLx)(Ti1-zMz)yNuOv (where 0<=x<=1, 0.8<=y<=1.4, 0<=z<=1, 0<=u<=0.5, 0<=v<=0.75, L is one or more among Cr, Mn, Ni, Co, Cu and Al, M is one or more among Zr, Hf and Va group elements, and N is one or more among Sc, Y, lanthanides and actinides). By the composition, the hydrogen storing metallic material is stabilized to oxygen, is easily activated, and has a high rate of hydrogenation.
