摘要

A method for making hydrogen storage alloy powder comprises quenching a melt of a hydrogen storage alloy, breaking the quenched alloy into fine pieces provided that said alloy is in non-powder form after the quenching, and subjecting the fine pieces to treatment with a solution containing a conjugated unsaturated compound which has five or more conjugated pi bonds in the molecule and a molecular weight of 100 or above.
