Abstract

A non-porous hydrogen diffusion membrane, and the utilization thereof for e separation of hydrogen from gas mixtures. The non-porous hydrogen diffusion membrane distinguishes itself in that it is constituted of TiNi or TiAg with an atom ratio of about 1:1. These titanium alloys presently contain about 45 to 55% of atoms of one or the other of the components and are utilized at temperatures in excess of 300.degree. C. in the form of thin sheets of foils.
