• Abstract:In this paper, La(0.8)Sr(0.2)MnO(3)-Ba(0.1)Bi(0.9)O(1.5-delta) (LSM-BSB) composite cathode was prepared and characterized for intermediate temperature solid oxide fuel cells (IT-SOFCs). XRD results show that no reaction occurred between LSM and BSB at 900A degrees C. SEM results show that the LSM-BSB composite cathode formed good contact with YSZ electrolyte after sintered at 900A degrees C for 2 h, which significantly reduced the sintering temperature of cathode. Compared with the LSM-YSZ electrode sintered at 1200A degrees C for 2 h, LSM-BSB electrode exhibits better electrochemical performance. At 800A degrees C, the area specific resistance (ASR) of the LSM-BSB30 electrode is about 0.168 Omega cm(2), which is nearly 1.5 times lower than that of LSM-YSZ composite cathode.
