Abstract
A novel method of producing an improved thin hydrogen-selective palladium-alloy membrane, through solid-solid interdiffusion of thin films or layers of palladium and a palladium-enhancing metal, such as copper, subjected in the presence of a reducing agent, such as hydrogen, to an elevated temperature below the melting point of both metals, for a sufficient time to effect substantially complete interdiffusion of the metals.
