Abstract With a 100% selectivity for hydrogen,the proton-electron mixed conducting separation membranes have great potential in the application of hydrogen separation and purification. Ni-BaCe0.7Y0.3-xTaxO3-δ (x=0, 0.05, 0.1) cermet hydrogen separation membranes were prepared by liquid phase method, and the hydrogen permeability and stability of the cermet membrane were tested. Both the conductivity and hydrogen permeability of BaCe0.7Y0.3-xTaxO3-δ (x=0, 0.05, 0.1) decrease under the wet 20vol% H2+80vol% N2 atmosphere with the increase of Ta element doping amount, which increases with increasing temperature. In the feed gas containing 3vol% CO2 and 10vol% CO2, the hydrogen permeability of Ni-BaCe0.7Y0.2Ta0.1O3-δ remained nearly stable, while the hydrogen permeability of Ni-BaCe0.7Y0.3O3-δ and Ni-BaCe0.7Y0.25Ta0.05O3-δ increase continually. This may be because the reaction between BaCe0.7Y0.3-xTaxO3-δ(x=0, 0.05) and CO2 is more severe and the product generated is not dense, which causes the effective thickness of the sample is reduced.
