Abstract
Composite hydrogen separation metal membranes are disclosed that contain an intermediate layer separating a base metal and a coating metal, wherein the intermediate layer is not a pure metal or metal alloy and is thermodynamically stable at operating temperatures.
Claims20
A hydrogen separation composite metal membrane which, after fabrication, comprises a nonporous hydrogen-permeable base metal and a nonporous hydrogen-permeable coating metal separated by a hydrogen-permeable intermediate layer, wherein said intermediate layer is not a pure metal or metal alloy, and at a temperature of from about 400.degree. C. to about 1000.degree. C. does not form a thermo-dynamically stable hydrogen-impermeable layer by reaction with hydrogen or by reaction with said base metal or with said coating metal.
