Hydrogen was introduced into Pd–Ag Pd77Ag23 membrane from a gas phase and self-stresses were created. The diffusion coefficients of H were determined for a Pd77Ag23 membrane with different initial contents of H at 303.2K. The non-local fluxes of interstitial component in the opposite direction than Fick’s fluxes were observed at stress conditions. The diffusion of H through the Pd77Ag23 membrane was compared with deuterium diffusion. For Pd77Ag23 membrane without initial content of hydrogen, the diffusion coefficients of H were determined at 298.2, 303.2, 308.2, 318.2 and 328.2K.
