Abstract
A dense palladium-nikel (Pd-Ni) alloy composite membrane has been fabricated on microporous nickel support mixed with submicron/micron nickel powder instead of mesoporous stainless steel support. Plasma treatment process is introduced as pre-treatment process instead of HCl activation. Pd-Ni alloy composite membrane prepared by electro plating was fairly a uniform and dense surface morphology. The membrane was characterized by permeation experiments with hydrogen and nitrogen gases at temperature 773K and pressure 2.2psi. The results showed that hydrogen (H2) permeance was 27ml/cm2atmmin and hydrogen/ nitrogen (H2/N2) selectivity was 8 at 773K.
