An intermediate temperature solid oxide fuel cell (ITSOFC) based on 8YSZ electrolyte, La 0 . 6 Sr 0 . 4 CoO 3 - δ (LSCo) cathode, and Ni - 8YSZ anode coatings were consecutively deposited onto a porous Ni-plate substrate by atmospheric plasma spraying (APS). The spray parameters including current, argon and hydrogen flow rate, and powder feed rate were investigated by an orthogonal experiment to fabricate a thin gas-tight 8YSZ electrolyte coating (80μm). By proper selection of the spray parameters to decrease the particles velocity and temperature, the sprayed NiO + 8YSZ coating after reducing with hydrogen shows a good electrocatalytic activity for H 2 oxidation. With the same treatment, 100-170μm dimensions LSCo particle could keep phase structure after spraying. And the deposited LSCo cathode shows a good cathode performance and chemical compatibility with 8YSZ electrolyte after operating at 800 o C for 50h. Output power density of the sprayed cell achieved 410mWcm - 2 at 850 o C and 260mWcm - 2 at 800 o C. Electrochemical characterization indicated that IR drop of 8YSZ electrolyte, cathodic polarization, and the contact resistance at LSCo/8YSZ interface were the main factors restricting the cell performance. The results suggested that the use of APS cell allowed the reduction of the operating temperature of the SOFC to below 850 o C with lower production costs.
