摘　　要：AB3型贮氢合金(A=稀土元素、Ca、Y或Mg,B=Ni、Al、Mn、Co、Fe等过渡族元素)是替代以LaNi5为代表的AB5型贮氢合金的重要候选材料之一。本文介绍了AB3型贮氢合金及其氢化物的结构特性,综述了国内外有关AB3型合金的开发、应用和研究进展,并指出需要解决的问题及发展方向。Intermetallic compounds AB3 （ A = rare earth, Ca, Mg or Y; B = transition metal, Al or Mn） are considered as one of the most important candidates to substitute LaNi5 based hydrogen storage alloys. In this paper, the crystallographic, thermodynamic and electrochemical properties of this AB3 family are reviewed. The problems to be solved are discussed and the direction for the future work is suggested.
