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.
Claims14
Hydrogen permeation apparatus comprising a membrane in the form of a hydrogen permeable metallic foil of not more than 100 microns in thickness, and first and second support means for the membrane disposed on either side of and in contact with the membrane, each said support means comprising a metal cloth having a mesh width of not more than 50 microns, said membrane being arranged between said first and second support means whereby the said foil does not sag, in use, within the mesh openings.
Hydrogen permeation apparatus comprising a membrane in the form of a hydrogen permeable membrane of not more than 100 microns thickness, and support means for the membrane disposed on either side thereof and in contact therewith, said support means comprising metallic fabric having a mesh width of not more than 50 microns, said metallic fabric having a diffusion-blocking metallic layer thereon for increasing stability of said permeable membrane at relatively high operating temperatures.
