Electrophoretic deposition of bi-layered LSM/LSM-YSZ cathodes for solid oxide fuel cell

► Bi-layered SOFC cathode was first prepared by EPD technique. ► Dependence of thicknesses of the layers on cathodic resistances was investigated. ► The optimal thickness of the LSM-YSZ layer was 4 μm at 600 °C. ► Cathode property at 800 °C mainly depended on the thickness of LSM layer.
