Impact of porous transport layer compression on hydrogen permeation in PEM water electrolysis
International journal of hydrogen energy, 2020Gas permeation through a membrane electrode assembly (MEA) is an important issue in the development of polymer electrolyte membrane (PEM) water electrolyzers, because it can cause explosions and efficiency losses.

Herein, the first observation of the effective hydrogen diffusion coefficient of CoCrFeMnNi high-entropy alloy (HEA) was performed using electrochemical hydrogen permeation; further, it was compared with those of stainless steels (SS) 304 and 316L.

Journal of Applied Physics, 1989
The permeation of deuterium (D) from the gas phase into solution in iron has been measured using a new method based on ion beam analysis. For bare metal surfaces the D uptake was observed to be limited by matrix diffusion through the bulk. The influence of chemisorbed oxygen on the D uptake rate was examined in detail.

Hydrogen Permeation Measurements on Alumina
Journal of the American Ceramic Society, 2004The aim of this work is to measure the hydrogen transport and solubility parameters in the commercial alumina. Measurements are conducted using a time‐dependent permeation method over the temperature range 1273–1673 K with hydrogen driving pressures in the range 10 4

Hydrogen permeation through graphite
Journal of Nuclear Materials, 1988Abstract 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 ...

Permeation of hydrogen through palladium
Journal of Nuclear Materials, 1995Abstract Palladium membranes have been bombarded by beams of ∼ 10 eV atomic hydrogen with a peak flux and fluence of 4 × 10 16 cm −2 s −1 and 10 20 cm −2 , respectively. The time-dependent permeation resulting from these exposures has been measured as a function of membrane temperature.

Hydrogen Permeation of Alloy 22
CORROSION 2008, 2008Abstract The effect of hydrogen permeation on the corrosion performance of Alloy 22 was investigated. 50µm thick Alloy 22 membranes were permeated with Hydrogen under a cathodic charging current density of 1mA/cm2 in a Devanathan-Stachurski cell at 60°C in pH 12.5, 0.1M NaOH solution.

The electro-permeation of hydrogen into metals
Electrochimica Acta, 1970Abstract It is sought to relate the diffusion coefficient and solubility for hydrogen in metals to the interaction of hydrogen with the metal phase. Determinations of permeation and diffusion coefficient have been made by a very sensitive electrochemical method at room temperature, and in some cases with temperatures up to 80°C, for platinum, nickel,

Permeation of hydrogen isotopes in nickel
The Journal of Physical Chemistry, 1978Tritium permeabilities of nickel over the 500 to 1100 K range have been determined and compared to deuterium and protium permeabilities. Solubility data for the three isotopes have been calculated from these permeability data and literature data for diffusivities.
