In the present study, La0.6Sr0.4Co0.2Fe0.8O3 (LSCF)-Gd0.1Ce0.9O1.95 (GDC) composite cathodes with different volume fractions were fabricated by screen printing method, and their polarization characteristics microstructure parameters are evaluated. Cathode overpotentials measured at measurement condition of 700 °C 100 % O 2 . Microstructures reconstructed focused ion beam-scanning electron microscope (FIB-SEM). The relationship between is quantitatively investigated.
