Abstract

In this study, hydrogen permeation behaviour was investigated for both dense and porous ceramic composite membranes. Selected porous supports were tested and highly active metallic species was impregnated into the porous structure using the repeated dip coating technique. Thin palladium films deposited onto a 15 nm pore size porous ceramic alumina support using both conventional and modified electroless plating methods were also studied. The hydrogen transport behaviours of the membranes were investigated, including the effect of high-temperature treatment including on the hydrogen transport. The value of the permeance in both the dense and porous systems were compared and the exponential factor n depicting the rate limiting step to hydrogen permeation in the dense membranes was also investigated. Deviations from Sievert’s Law were observed from the palladium membranes when compared to the porous systems investigated in this work.
