摘要： For economically storing relatively large quantities of hydrogen, a hydrogen storage material comprises (1) a major R 2 Fe 17 phase wherein the R is lanthanum, cerium and, optionally, other rare earth(s) such as praesodymium and neodymium, (2) an R'/R'Fe 2 eutectic where R' is lanthanum-starved R, (3) an unalloyed lanthanum phase, and (4) an unalloyed iron phase. The material contains less than 55% by weight cerium based on the total weight of cerium, lanthanum and other rare earth(s). Such a material is produced by an homogenising heat treatment.
