采用电泳沉积法（EPD）在NiO-SDC阳极衬底上制备了Ce0.8Sm0.2O1.9 （SDC）电解质膜，用于中温固体氧化物燃料电池（sofc）。通过与衬底共烧，制备了致密无裂纹的薄膜。采用La0.6Sr0.4CoO3-δ阴极的SDC电解质膜的电池在600℃下的功率密度为281 mW/cm2，电解质电阻为0.064 cm2。EPD在SDC上形成薄膜，可以有效地降低电解质电阻。
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 600°C. The film formation of SDC by EPD was found effective in decreasing the electrolyte resistance.
