摘要：
The invention relates to a rare earth based hydrogen storage alloy, represented by the general formula (I): RExYyNiz-a-b-cMnaAlbMcZrATiB (I) wherein RE denotes one or more element(s) selected from La, Ce, Pr, Nd, Sm, Gd; M denotes one or more element(s) selected from Cu, Fe, Co, Sn, V, W. The alloy has favorable pressure-composition-temperature characteristic, high hydrogen storage capacity, high electrochemical capacity. The alloy doesn't contain magnesium element, and the preparation process of the alloy is easy and safe.
