摘要: Composite membranes consisting of a proton-conducting ceramic and an electronic conductor are promising in reducing the cost separation hydrogen from CO2. However, lack stable CO2 with sufficient proton conductivity remains great hurdle. In this study, we investigated permeation performance chemical stability composite based on doped ceria Ni. Doped used to be considered as very poor for long time. our results show that heavily rare earth element possesses significant conductivity. Compared perovskite-type oxides, fluorite-type much higher H2O
