A review of electrophoretic deposition of metal oxides and its application in solid oxide fuel cells.

Because of its cost-effectiveness, good uniformity, fast deposition rate and simplicity, electrophoretic deposition (EPD) has been widely used to deposit various metal oxide films for different applications. As with other coating fabrication processes, the deposition rate and film quality are two crucial criteria to evaluate the effectiveness and suitability of EPD. In this review, we summarize the parameters and discuss the dynamic processes influencing the deposition behavior of ionically charged metal oxide particles. Special focus is also given to the methods to improve the film quality. In addition, the application of EPD in the fabrication of solid oxide fuel cells (SOFCs) is summarized.
