Abstract

A novel in situ Pr diffusion strategy based on a Sm0.2Ce0.8O2−δ–Pr(Pr0.5Ba1.5)Cu3O7−δ (3 : 7 wt%) compound is developed to achieve a perovskite-related proton-blocking composite cathode Ce1−xPrxO2−δ–Ba2CeCu3O7.4–Sm2Ba1.33Ce0.67Cu3O9–CuO for BaZr0.1Ce0.7Y0.2O3−δ-based proton-conducting SOFCs.
