Abstract
A leak-proof membrane element () for the selective separation or cleaning of gas, wherein a metal foil (membrane) () is deposited onto a supporting stock (substrate) () having connection means () on the ends/edges of the substrate allowing the membrane element to be installed in a housing. A metal foil (), having a thickness of less that 10 micrometers and being selectively permeable for specific gases, is arranged in flakes or wound with overlapping joints () on the outside of the substrate (), any joints being welded together by diffusion bonding so that the foil forms a continuous, leak-proof metal membrane layer. The substrate being made of a material (metal, ceram, polymer, or combinations thereof) exhibiting a very high gas flux for the gas(es) that the membrane is to let through.
