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.

[ What is claimed is:] [1.]1. The method of producing a thin hydrogen-selective palladium-alloy membrane comprising the steps of physically contacting thin solid specimens consisting of palladium metal with thin solid specimens consisting of an interdiffusing palladium-enhancing metal, and subjecting the same in the presence of reducing agent to an elevated temperature below the melting point of both metals but above about 300.degree. C. for a sufficient period of time to effect substantially complete solid-solid interdiffusion of said metals. [3.]3. The method of claim 1 wherein the reducing agent is hydrogen and the palladium-enhancing metal specimen is one of copper and silver. [7.]7. A thin hydrogen-selective palladium alloy membrane of palladium and copper formed by the method of claim 3.
