Permeation and trapping of hydrogen in Eurofer97

Nuclear Materials and Energy, 2021
Diffusion and trapping of hydrogen isotopes in fusion materials need to be fully described in order to evaluate permeation and retention in fusion reactors walls and breeding blankets. Hydrogen gas permeation experiments have been conducted on Eurofer97 with pressures ranging from 101to 105Pa and temperatures between 473 K and 673 K, resulting in ...

Microfabrication of palladium-silver alloy membranes for hydrogen separation [PDF]

, 2003
In this paper, a process for the microfabrication of a wafer-scale palladium-silver alloy membrane (Pd-Ag) is presented. Pd-Ag alloy films containing 23 wt% Ag were prepared by co-sputtering from pure Pd and Ag targets.

Reduced complexity models for water management and anode purge scheduling in DEA operation of PEMFCs [PDF]

, 2010
In this work, the dynamic behavior of Fuel Cell operation under Dead-Ended Anode conditions is shown. A DEA can be fed with dry hydrogen, since water crossing through the membrane is sufficient to humidify the fuel.
