HYDROGEN STORAGE MATERIAL, HYDROGEN STORAGE CONTAINER AND HYDROGEN SUPPLY DEVICE

Provided are a hydrogen storage material containing a TiFe-based alloy that is favorably initially activated and has a sufficient amount of releasable hydrogen, a hydrogen storage container including the hydrogen storage material, and a hydrogen supply apparatus including the hydrogen storage container. Specifically, there are provided a hydrogen storage material containing an alloy of a specific elemental composition represented by Formula (1) below, in which, in a 1000 times magnified COMP image of a cross section of the alloy obtained by EPMA, 25 or more and 3000 or less pieces of a phase in which R is enriched and that have phase sizes of 0.1 µm or more and 10 µm or less are present in a field of view of 85 µm × 120 µm of the COMP image, and an R-enriched phase area ratio of the total area SR µm2 of the pieces of the phase present in the field of view to the area S µm2 of the field of view is 0.3% or more and 6.0% or less, a hydrogen storage container including the hydrogen storage material, and a hydrogen supply apparatus including the hydrogen storage container.
