| Abstract | Electrolyte films of Ce0.8Sm0.2O1.9 (SDC) were prepared on NiO-SDC anode substrates by electrophoretic deposition (EPD) for intermediate-temperature solid oxide fuel cells (SOFCs). Dense and crack-free films were fabricated by cofiring the films and substrates. A cell using an SDC electrolyte film with a La0.6Sr0.4CoO3-δ cathode exhibited a power density of 281 mW/cm2 and an electrolyte resistance of 0.064 cm2 at 600ºC. The film formation of SDC by EPD was found effective in decreasing the electrolyte resistance. |
