Abstract
No investigation has yet been accomplished to screen the yttrium-doped effects on vanadium-based metal membranes. Synthesis, hydrogen permeation properties, and chemical stability of a novel palladium (Pd)-coated V 99Y 1 alloy membrane are presented. Hydrogen permeation experiments have been performed to investigate the hydrogen transport properties through the Pd-coated V 99Y 1 alloy membrane in the pressure range of 1.5-3.0bar under pure hydrogen as well as H 2-CO 2 and H 2-CO gas mixtures at 400°C. The maximum hydrogen permeation rate was ~32mLmin -1cm -2 for a 0.5mm thick membrane under pure hydrogen. The results offer new directions in the synthesis of novel non-Pd-based metal membranes for hydrogen separation in precombustion capture applications.
