dc.description.abstractThe electrochemical properties and microstructural change of deposited films of a mixed electronic-ionic conductor (MIEC) consisting of strontium-doped samarium cobaltite (Sm0.5Sr0.5CoO3, SSC) for cathode electrodes of SOFCs was studied by using electrostatic spray deposition (ESD). It is observed that the morphology of the deposited films strongly depended on the various process parameters of the ESD such as the deposition temperature, applied voltage, deposition time, and distance between nozzle and substrate. With specific deposition condition, a gradient porous SSC film, which is nano-porous close to the electrode/electrolyte interface and micro-porous close to the electrode surface, and nano-porous film were prepared on the SDC electrolyte. The electrochemical properties of the prepared SSC/SDC half-cell were investigated at operating temperature of 600 ~ 750 oC. The half-cell which had the gradient porous microstructure showed lower polarization resistance and the activation energy than that of the half-cell which had uniform porosity in the cathode film.-
