Hydrogen Permeation through Nickel
Japanese Journal of Applied Physics, 1984The time dependence of the rates of permeation of hydrogen through annealed and as-rolled nickel foils was measured in the temperature ranges 120–430°C and 80–200°C, respectively. Annealed specimens exhibited permeabilities, diffusivities and solubilities that were in fairly good agreement with previous results, while the permeation characteristics of ...

Effect of trapping on hydrogen permeation
Metallurgical Transactions A, 1975Approximate solutions were obtained to the nonlinear partial differential equations derived by A. McNabb and P. K. Foster for a general model of diffusion-plus-trapping. The finite-difference method was applied to their equations for boundary conditions appropriate to hydrogen permeation and evolution in a plane. Solutions are shown to be stable and to

Hydrogen permeation characteristics of La27Mo1.5W3.5O55.5
Journal of Membrane Science, 2014Abstract Hydrogen permeation in 30% Mo-substituted lanthanum tungsten oxide membranes, La27Mo1.5W3.5O55.5 (LWMo), has been measured as a function of temperature, hydrogen partial pressure gradient, and water vapor pressure in the sweep gas. Transport of hydrogen by means of ambipolar proton–electron conductivity and – with wet sweep gas – water ...

Hydrogen permeation and diffusion in niobium
Metallurgical Transactions A, 1983High temperature hydrogen permeation experiments were performed on niobium using ultra high vacuum techniques in an attempt to maintain clean specimen surfaces. Diffusivities and permeabilities were measured from 700 K to about 1400 K at hydrogen pressures ranging from 4.26 Pa to about 0.013 Pa.

Vanadium carbide coating as hydrogen permeation barrier: A DFT study
International journal of hydrogen energy, 2019Density functional calculations are used to investigate hydrogen (H) behaviors in vanadium carbide (VC). Molecular H2 dissociation, atomic H diffusion and penetration are analyzed using the transition state theory.
