Date Nov. 6, 1997Method for manufacturing a composite membrane structure comprising a thin metal membrane, for example of silver, palladium or palladium alloys, for use in selective diffusion of gasses. The metal material for the membrane is applied by sputtering as a coating on a base member having a low surface roughness, to a desired thickness of the resulting coating. The coating is pulled off from the base member so as to form the metal membrane, and the metal membrane is placed on a supporting substrate. |
