Mathematical simulation of atomic hydrogen diffusion transfer through a bimetallic membrane

Abstract

Mathematical simulation of atomic hydrogen diffusion transfer through a bimetallic membrane is performed under the approximation of an ideal lattice gas. Analytical expressions are derived for diffusion fluxes at different membrane orientations. The intensity of diffusion transfer of hydrogen atoms through a bimetallic membrane depends on the direction of transfer, provided that they have different solubilities in metal layers. It is shown that the effect of diffusion asymmetry must be taken into account when developing and using bimetallic membranes.
