Abstract

A method for producing a tubular hydrogen permeation membrane comprising: (a) adhering at least one layer containing palladium, at least one palladium alloy, platinum, or at least one platinum alloy to a first surface of a plate having such first surface and a second surface disposed opposite to the first surface, the plate being of a metal or a metal alloy containing at least one metal from a group of the Periodic System of Elements selected from the group consisting of the fourth secondary group and the fifth secondary group, to form a layered plate; and (b) reshaping the layered plate into a tubular hydrogen permeation membrane having an inside wall, so that the layer adhered to the first surface is disposed on the inside wall of the tubular hydrogen permeation membrane.
