Summary: Perovskite-type cathode Ba1-xCo0.7Fe0.2Nb0.1O3-delta (B1-xCFN, x = 0.0-0.15) shows a cubic perovskite structure with decreasing porosity as A-site deficiency increases, and the interfacial polarization resistance of B0.9CFN drops significantly at 800 degrees Celsius. Additionally, lattice oxygen generation is the major rate-limiting step when oxygen partial pressure is higher than 0.01 atm, and Ba deficiency accelerates the ionization process of oxygen atoms in the cathode bulk. The performance of single-cell B0.9CFN/SDC/Ni0.9Cu0.1-SDC is superior to other cathodes at operation temperature, indicating B0.9CFN as a better cathode for IT-SOFC.
