BaCe0.7Zr0.1Y0.2O3-delta (BCZY) electrolyte and La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF) cathode perovskite materials were synthesised using the citrate-nitrate combustion method. NiO-BCZY anode supported thin film sold oxide fuel cells (SOFCs) was fabricated using spin coating and co-sintering process. LSCF exhibited good chemical stability in H2O containing atmosphere and chemical compatibility with BCZY proton conducting material. The electrochemical performance of the Ag-LSCF composite cathode was dependent on the Ag content. The thin film proton conducting SOFC displayed highest maximum power density of 563 mW cm(-2) at 700 degrees C for 10 wt-%Ag-(LSCF + BCZY) composite cathode.
