(La, Sr)MnO3 (LSM)-Y doped ZrO2 (YSZ) Composite was prepared using YSZ colloidal suspension (initial YSZ particle size similar to 100 nm), YSZ and LSM polymer precursors on dense substrates at 800 degrees C annealing temperature. The results of a symmetrical LSM-YSZ composite cell test showed the area specific resistance for overpotential of 0.14 Omega cm(2) at 800 degrees C, which indicated that the LSM-YSZ composite could be a potential candidate for cathode in SOFCs. The performance of the cell with the LSM-YSZ composite cathode and Ni-YSZ anode was investigated and the power density of about 0.26 W cm(-2) was obtained at 850 degrees C using hydrogen fuel.
