ABSTRACT:
The present invention discloses a type of novel material compositions for hydrogen storage. The material compositions includes a hydrogen storage Laves-phase alloy which has a material composition represented by A.sub.1-X B.sub.X C.sub.Y where A=(Zr or Hf).sub.1-X1 Ti.sub.X1 and X1 has a value between zero to one, B=La, Ce, Pr, Nd and mixed rare earth, alkaline, or alkaline earth metallic element, C=V.sub.Y1 Ni.sub.Y2, where Y1 has a value between zero to 0.8, Y2 has a value between 1.3 to 3.0, and X has a value between zero to 0.2 and Y has a value between 2.0 to 3.0. In a preferred embodiment, when the value of X is greater than zero, the Laves-phase alloy includes a plurality of B--Ni clusters.
