摘要

Anode-supported solid oxide fuel cells (SOFC) with yttria stabilized zirconia (YSZ)-samarium doped ceria (SDC) bi-layer electrolyte thin films and La_(1-x)Sr_xCoO_(3-δ) (LSC) + SDC composite cathodes were fabricated. Dense YSZ-SDC bi-layer electrolyte films were prepared to prevent a chemical reaction between LSC and YSZ at high temperatures. Composition, distribution of the two phases and microstructure of the LSC + SDC composite electrodes were varied by varying processing conditions in an attempt to minimize the cathodic overpotential. The composite cathode with 40 wt% LSC + 60 wt% SDC exhibited the best performance. Power density achieved was as high as 1.8 W/cm~2 at 800℃. Although the cathode overpotential was lower than that for the LSM + YSZ composite cathode, it was still the dominant factor limiting the cell performance. LSC + SDC composite appears to be a promising cathode for SOFC operating at 800℃, and possibly at lower temperatures.
