Abstract

Electrophoretic deposition (EPD) is a colloidal process wherein ceramic bodies are directly shaped from a stable colloid suspension by a dc electric field. Compared to other advanced shaping techniques, the EPD process is very versatile since it can be modified easily for a specific application. The EPD is also gaining increasing interest as a processing technique for production of novel inorganic nanostructured and nanoscale materials. In this paper, the deposition mechanism of the EPD process and its application on SOFC is introduced.
