Hydrogen storage material, hydrogen storage container, and hydrogen supply apparatus

Abstract

Provided are hydrogen storage materials having hydrogen absorption (storage) desorption properties suitable for hydrogen storage in a temperature range of 0° C. or lower. Also provided are a hydrogen storage container containing the hydrogen storage materials, and a hydrogen supply apparatus including the hydrogen storage container. The hydrogen storage materials have an alloy with an elemental composition represented by Formula (1): in Formula (1), M is at least one kind selected from Mn, Co, and Al and essentially contains Mn, a satisfies 0.00≤a≤0.62, b satisfies 0.20≤b≤0.57, c satisfies 0.17≤c≤0.60, d satisfies 4.50≤d≤5.20, e satisfies 0.15≤e≤0.70, a+b+c=1, c+e satisfies 0.55≤c+e≤1.20, and d+e satisfies 5.13≤d+e≤5.40.
