A Study on the Palladium Alloy Membrane for Hydrogen Separation Woo, Byung-Il; Kim, Dong-Won;
This study presented the effect of membrane thickness on hydrogen permeability. Microvoids on the surface of the membrane should not exist for the exact values of hydrogen permeability. Pd-Cu-Ni hydrogen alloy membranes were fabricated by Ni powder sintering, substrate plasma pretreatment, sputtering and Cu reflow process. And this leaded to void-free surface and dense film of Pd-Cu-Ni hydrogen alloy membrane. Hydrogen permeation test showed that hydrogen permeability increased from 2.7 to as membrane thickness decreased from 12 to . This represented the similar trend as a hydrogen permeability of pure palladium membrane based on solution-diffusion mechanism.
