摘要：

A material with perovskite structure, lanthanum strontium cobaltite ferrite, La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF6428) has gained attention as a cathode component for intermediate to low temperature solid oxide fuel cells (IT-LTSOFCs). In this study, LSCF6428 films were developed via the electrophoretic deposition (EPD) technique with the use of an aqueous solvent. 1 wt% of LSCF6428 was suspended in deionised water for the preparation of the EPD suspensions. The EPD process at applied voltages of between 3 to 7 V and deposition times of 3 to 10 minutes has been found to be able to deposit LSCF6428 films. Additionally, the use of additives such as starch and polymethyl methacrylate (PMMA) was found to effectively improve the quality of the deposited films. It is concluded that the applied voltage, deposition time and the addition of additives play important roles that affect the morphology and weight of the deposited films.
