Abstract Scope |
Solid oxide fuel cells (SOFCs) exhibit performance degradation by ‘chromium poisoning’, where thermally grown Cr2O3 on stainless steel components form volatile Cr-containing species that are redeposited on active regions of the cathode. With porous substrates that have a large surface area to volume ratio, this effect can be more pronounced. Electrophoretic deposition (EPD) of spinel protective coatings on porous SUS430 metallic substrates using alternating current (AC) has been carried out. It is demonstrated that alternating current electrophoretic deposition (AC-EPD) was able to deposit protective coatings on all surfaces of porous substrates, that significantly limited the growth rate of the thermally grown oxide on the stainless steel substrates. |
