The diffusion of hydrogen and deuterium through self-stressed Pd77Ag23 membrane

Hydrogen was introduced into palladium-silver Pd77Ag23 membrane from a gas phase and self-stresses were created. The diffusion coefficients of hydrogen were determined for Pd77Ag23 membrane with different initial contents of hydrogen at T=303.2 -bar K. The non-local fluxes of interstitial component in the opposite direction than Fick's fluxes were observed at stress conditions. The diffusion of hydrogen through the Pd77Ag23 membrane has been compared with deuterium diffusion. For Pd77Ag23 membrane without initial content of hydrogen, the diffusion coefficients of hydrogen were determined at temperatures: 298.2, 303.2, 308.2, 318.2, 328.2-bar K
