Abstract
Stainless steel solid oxide fuel cell (SOFC) interconnects can lead to chromium poisoning of the cathode, necessitating the use of protective coatings. Electrophoretic deposition (EPD) is an efficient method to deposit coatings on substrates with complex microstructures. In this study, four spinel coatings; CuMn2O4, CuNi0.2Mn1.8O4, MnCo2O4, and MnFe0.34Co1.66O4, were electrophoretically deposited, and the coatings were evaluated on multiple criteria; including microstructural stability, conductivity, Cr gettering ability, and the ability to act as a diffusion barrier. The relative rankings of these measured properties for the four coatings will be discussed in this presentation.
