英文摘要 | hydrogen permeation performance of three thin palladium- copper composite membranes with different thicknesses had been studied between 398 k and 753 k. hydrogen permeance was obtained up to 2.7 x 10(-6) mol/(m(2) s pa) with an ideal selectivity over 1000 at 753 k. the hydrogen permeation exhibited two different activation energies over the temperature range: lower activation energy of about 9.8 kj/mol above 548 k, while higher activation energy of about 26.4 u/mol below 548 k. after permeation tests, the alloy membranes were characterized by x-ray photoelectron spectroscopy, scanning electron microscopy, energy dispersive x-ray analysis and in situ x-ray diffraction. palladium segregation on the surface of these palladium-copper alloys may induce changes of hydrogen permeation performance and thus influence the activation energies.
