Hydrogen absorbing alloys with BCC (body centered cubic) structure such as Ti-V-Mn, Ti-V-Cr and Ti-V-Cr-Mn systems were proposed and named as "Laves phase related BCC solid solution" by Akiba in 1993. Since our reports, many researchers have developed BCC hydrogen absorbing alloys. These alloys have higher hydrogen capacity (about 2.8 mass% at present) than conventional intermetallic compounds. Many efforts have been made to increase hydrogen capacity of the alloys but fundamental studies were a few. Crystal structure and morphology of the BCC alloys that are keys to understand BCC hydrogen absorbing alloys are reviewed.
