This article reviews the recent progress in hydrogen absorption alloys. Firstly, the mechanism of the hydrogen storage in hydrogen absorption alloys is briefly described. Secondly, the chemical composition, crystal structures, hydrogen absorption properties of typical binary intermetallic compounds are summarized. Finally, the merits and the demerits of novel hydrogen absorption alloys, i.e. BCC solid solution alloys, Mg-based alloys and compounds and PuNi₃-type ternary compounds, are discussed.
