(LSCF) porous cathode layer and Ni–SDC anode functional layer for anode-supported SOFCs are fabricated by a slurry spin coating tech- nique. The optimum conditions for preparing the single cell with a uniform microstructure as well as excellent performance have been investigated. A dense electrolyte thin filmwith a crack-freemicrostruc- ture can be obtained by using the SDC powders pre-calcined at 900 ?C. The power density of the cells increases with the increasing weight content of corn starch (corn starch wt.%), which is mainly ascribedlurry spin coating ore former node functional layer oncentration loss olarization resistance to the decrease of the concentration loss in the anode. However, the trade-off between the single cell performance andmechanical strength results in the optimumcomposition being obtained for theNi–SDC anode containing 15wt.% corn starch (15-Ni–SDC). In contrast to the data in the literatures, the relatively large ohmic resistance (Rohm) values in the present study are obtained for the 15-Ni–SDC cell. In order to further improve the cell performance, an
