Hydrogen-permeable structure and a manufacturing method thereof

Hydrogen-permeable structure comprises a substrate comprising a ceramic porous (1), is formed on the substrate (1), and at least one element other than palladium palladium (Pd), and a predetermined hydrogen dissolution amount at a temperature of and a small hydrogen-permeable membrane than palladium alone (2). Forming a hydrogen-permeable membrane (2) by physical vapor deposition on a surface of a substrate comprising a ceramic porous (1).
