Beschreibung
Zusammenfassung:	A low-cost hydrogen storage material has hydrogen absorption (storage) and desorption properties suitable for hydrogen storage. A hydrogen storage container including the hydrogen storage material and a hydrogen supply apparatus including the hydrogen storage container are disclosed. The hydrogen storage material includes an alloy having a specific elemental composition represented by Formula (1), in which, in a 1000×COMP image of a cross section of the alloy obtained by EPMA, a plurality of phases enriched with R are present, the phases having phase diameters of 0.1 μm or more and 10 μm or less, and 100 or more sets of combinations of two phases in the phases are present in a visual field of 85 μm×120 μm in the COMP image, the shortest separation distance between the two phases being 0.5 to 20 μm.[Chem. 1]Ti(1-a-b)RaM1bFecMndM2eCf (1)
