Abstract
Highly electrochemical performance and CO<sub>2</sub>durability are two challenges for exploring cathodes in SOFCs. A new type of Ba<sub>0.9</sub>Co<sub>0.7</sub>Fe<sub>0.2</sub>M<sub>0.1</sub>O<sub>3−δ</sub>(M = Zr, Nb, Y) perovskites as promising cathode for IT-SOFCs has been developed with cations doping.
