Composition comprising hydrogen storage alloy and resin

摘要

A resin composition including a resin and a hydrogen storage alloy powder. When hydrogen gas is absorbed-released in a hydrogen storage vessel obtained by filling the resin composition in the vessel such that a ratio V2/V1 between a volume V2 of the hydrogen storage alloy powder and an inner volume V1 of the vessel becomes 40 to 80 vol %, a distortion alpha produced on a wall of the hydrogen storage vessel is 1,000×10-6 or less.
