The symmetric cell of LaNi0.6Fe0.4O3-δ/Sc0.1Zr0.9O1.95/LaNi0.6Fe0.4O 3-δ was fabricated with screen printing method. A LaNi0.6Fe0.4O3-δ (LNF) cathode was modified by coating with nano-sized gadolinium-doped ceria (GDC, Gd0.2Ce0.8O2) prepared using a simple combustion process within the pores of the cathode. According to the electrochemical impedance spectra (EIS), the polarization resistance of the pure LNF was 0.70 W·cm2 at 750 ºC, while 0.13 W·cm2 for the 21.3% GDC (by mass)-coated LNF …
