Summary: The effect of A-site doping on the oxygen reduction reaction activity and stability in perovskite cathodes is studied by evaluating symmetrical and single cells. Ca-doped PBC (PBCC) exhibits slightly smaller polarization resistance and lower degradation rate compared to Sr-doped PBC (PBSC) in wet air. Additionally, single cells with PBCC cathode show higher peak power density and better durability than those with PBSC cathode, possibly due to a fast and stable surface oxygen exchange process.
