Diffusion membrane and process for separating hydrogen from gas mixture



Diffusion membrane and process for separating hydrogen from gas mixture



United States Patent (4,496,373): 7



Hydrogen and its isotopes are separated by diffusion through a non-porous hydrogen-permeable metallic membrane virtually impermeable to other gases. The membrane is provided on the gas access side with a coating of an alloy of palladium with <more or => 45 atomic % Cu or <more or => 50 atomic % Ag or <more or => 7 atomic % Y.
