COMPOSITION COMPRISING HYDROGEN-ABSORBING ALLOY AND RESIN

摘要

PROBLEM TO BE SOLVED: To provide a resin composition comprising a resin and a hydrogen-absorbing alloy powder, having characteristics for sufficiently suppressing the stress applied on the wall of a hydrogen storage container without impairing a high hydrogen storage capacity even when the hydrogen-absorbing alloy powder is filled in a large quantity per unit volume.

SOLUTION: In the resin composition (C) comprising a resin (A) and a hydrogen-absorbing alloy powder (B), a hydrogen storage container (E) can be produced by packing the resin composition (C) into a container (D) in such a manner that the ratio [(V2)/(V1)] of the volume (V2) of the hydrogen-adsorbing alloy powder (B) to the inner volume (V1) of the container (D) becomes 40 to 80 Vol%. When hydrogen gas is absorbed in and released into the hydrogen storage container (E), the strain (α) produced on the surface of the wall of the hydrogen storage container becomes ≤1,000×10-6.
