Abstract:
A defect-free hydrogen separation membrane includes a metal thin membrane. The metal thin membrane includes a first metal layer composed of palladium on a porous support without substantial penetration into surface pores of the porous support and a second metal layer on the first metal layer. The second metal layer is a product of palladium deposition and closes defects being open on the surface of the first metal layer.
