Abstract

A hydrogen permeation membrane in the form of a metal coating such as palium and alloys of palladium less than 100 microns in thickness supported by a fabric with a mesh width not exceeding 50 microns. A diffusion blocking material such as nickel and alloys of nickel may be provided. The metal coating may be in the range of about 10 to 30 microns, and the mesh width may be in the range of about 2 to 20 microns.
