Hydrogen permeation through graphite

Journal of Nuclear Materials, 1988
Abstract As a study of the transport processes of hydrogen in graphite, the kinetics of permeation of hydrogen and argon through graphite was investigated in the pressure range of 0.5 to 100 Pa and in the temperature range of 290 to 983 K. The observed results suggested that the hydrogen permeation through graphite can be dealt with as a simple ...

Hydrogen Permeation through Nickel

Japanese Journal of Applied Physics, 1984
The 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 ...

Hydrogen permeation through magnesium

Journal of Alloys and Compounds, 1999
Abstract Hydrogen permeation characteristics have been investigated for pure magnesium membranes with a palladium overlayer using a gas permeation technique in the temperature range 473–493 K and in the hydrogen pressure range 0.1–10 kPa. For thicker specimens (thickness >2 mm), the permeation process was rate-controlled by the diffusion of hydrogen ...

Perturbed hydrogen permeation of a hydrogen mixture—New phenomena in hydrogen permeation by Pd membrane

International Journal of Hydrogen Energy, 2008
Abstract The newly developed constant concentration method was adopted to study the hydrogen permeation of a hydrogen mixture of H 2 + Y through a palladium membrane tube. The hydrogen permeation of the hydrogen mixture differs from that of a single hydrogen feed. For the hydrogen mixture, the well-known Sieverts equation, Q = J
