The　modified　Pechini　method　was　applied　to　prepare　a　highly　active　and　novel　cathode　material　La0.7Sr0.3Ti0.15Fe0.65Ni0.2O3-delta　(LSTFN).　This　material　was　coated　on　the　LGSM　electrolyte　through　a　screen-printing　technique　with　variable　thicknesses　of　28　+/-　8,　41　+/-　8,　and　62　+/-　8　mu　m,　respectively.　Different　fabrication　parameters,　including　sintering　temperature,　time,　coating　thickness,　and　variations　in　ball-milling,　which　affect　the　electrochemical　performance　of　the　cathode　material,　were　investigated.　X-ray　diffraction　analysis　of　the　cathode　material　suggested　that　it　exhibits　a　cubic　crystal　structure　with　a　LSTFN　single　phase.　The　morphological　studies　were　conducted　using　scanning　electron　microscopy　(SEM),　which　confirmed　that　the　electrode　material　had　a　highly　porous　structure.　Meanwhile,　the　electrochemical　properties　of　the　material　were　studied　by　electrochemical　impedance　spectroscopy　(EIS),　which　revealed　that　by　varying　different　parameters,　the　electrochemical　performance　of　the　electrode　material　was　enhanced.　The　coated　cathode　materials　with　variable　thicknesses　were　analyzed　at　different　sintering　temperatures　and　times.　Experimental　results　suggest　that　the　optimum　sintering　temperature　and　time　were　950　degrees　C　and　3　h,　respectively,　at　which　LSTFN　exhibits　the　minimum　polarization　resistance　(R-P)　of　0.046　Omega　cm(2)　when　sintered　at　800　degrees　C　for　3　h.
