Hydrogen-permeable structure and method for manufacture thereof or repair thereof

摘要

The invention provides a hydrogen permeable structure, which can effectively prevent peeling-off of a hydrogen permeable film and hence has higher durability, and a method of manufacturing the structure.The hydrogen permeable structure has a hydrogen permeable film formed on the surface of or inside a porous support, having a thickness of not more than 2 mum, and containing palladium (Pd). The hydrogen permeable film is formed on the surface of or inside the porous support by supplying a Pd-containing solution and a reducing feed material from opposite sides of the porous support.
