A review on the solid oxide fuel cells (SOFCs) interconnect coating quality on electrophoretic deposition (EPD) processing parameters

Abstract

Solid oxide fuel cells (SOFCs) are one of the hit in the sustainable energy industry as it provides an efficient energy production through heat and the chemical reaction of fuel cell stacks (anode, cathode, electrolyte) to produce electrical energy and are connected via interconnects. SOFCs interconnects functions as a barrier for gas that sections the air (cathode electrode) and hydrogen (anode electrode) on the adjacent repeating unit cell. Electrophoretic deposition (EPD) is preferred as it provides an easy, cost effective and geometrically flexible colloidal process. Due to its excellent control of thickness and surface morphology, it is suitable as each component layers of SOFCs have different requirements. As to optimize EPD parameters, time deposition and voltage deposition is crucial as this affects the deposition rate of coating and coating quality. Thus, further discussion is to be implemented in this paper on the EPD mechanism in improving the effectiveness of SOFCs.
