Abstract: PROBLEM TO BE SOLVED: To provide a hydrogen storage material with a low hydrogen releasing temperature of 300°C or lower without requiring a complicated process such as a coating treatment to metal powder and to provide a method for producing the same.
SOLUTION: A hydrogen-storage body is provided, which is a laminated body containing a thin-film hydrogen-occluding layer on a substrate where compressive strain is applied to the hydrogen-occluding layer for applying bending deformation so that the substrate comes outside and the hydrogen-occluding layer comes inside. The method for producing the hydrogen storage body is characterized in that the bending deformation is applied to the laminated body so that the substrate comes outside and the hydrogen-occluding layer comes inside for applying compressive strain to the hydrogen occluding layer.
