COMPOSITION COMPRISING HYDROGEN STORAGE ALLOY AND RESIN

摘要

An object of the present invention is to provide a resin composition including a resin and a hydrogen storage alloy powder and ensuring that even when the amount of the hydrogen storage alloy powder filled per unit volume is high, uniform mixing with the resin is achieved and the stress applied to the wall of a hydrogen storage vessel is sufficiently suppressed without impairing the high hydrogen storage capacity. The present invention provides a resin composition (C), that is, a resin composition (C) including a resin (A) and a hydrogen storage alloy powder (B), wherein when hydrogen gas is absorbed-released in a hydrogen storage vessel (E) obtained by filling the resin composition (C) in a vessel (D) such that a ratio (V2)/(V1) between a volume (V2) of the hydrogen storage alloy powder (B) and an inner volume (V1) of the vessel (D) becomes 40 to 80 vol%, a distortion a produced on a wall of the hydrogen storage vessel (E) is 1, 000x10 -6 or less.
