Title:
HYDROGEN STORAGE MATERIAL, HYDROGEN STORAGE CONTAINER, AND HYDROGEN SUPPLY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/230817
Kind Code:
A1
Abstract:
Provided is a hydrogen storage material which has hydrogen occlusion (storage) release properties suitable for hydrogen storage purposes even in a temperature range of 0°C or lower. Also provided are: a hydrogen storage container provided with the hydrogen storage material; and a hydrogen supply apparatus provided with the hydrogen storage container. More specifically provided are: a hydrogen storage material containing an alloy having an elemental formula represented by formula (1); a hydrogen storage container provided with the hydrogen storage material; and a hydrogen supply apparatus provided with the hydrogen storage container. [In formula (1), M represents at least one element selected from Mn, Co and Al and essentially contains Mn, and a satisfies the formula: 0.00 ≦ a ≦ 0.62, b satisfies the formula: 0.20 ≦ b ≦ 0.57, c satisfies the formula: 0.17 ≦ c ≦ 0.60, d satisfies the formula: 4.50 ≦ d ≦ 5.20, and e satisfies the formula: 0.15 ≦ e ≦ 0.70, in which a+b+c = 1, c+e satisfies the formula: 0.55 ≦ c+e ≦ 1.20, and d+e satisfies the formula: 5.13 ≦ d+e ≦ 5.40.]
