Synthesis of (La,Sr)MnO{sub 3}-YSZ composite particles by spray pyrolysis
- Japan Fine Ceramics Center, Nagoya (Japan)
The authors have been developing a cathode material for solid oxide fuel cells (SOFCs) by the pyrolysis method. The unit cell of SOFCs consists of two porous and gas diffusion electrodes (cathode and anode) separated by a dense electrolyte such as yttria-stabilized zirconia (YSZ), which has a high ionic conductivity. Generally, the perovskite (La,Sr)MnO{sub 3} has been used mostly as a cathode material. (La{sub 0.8}Sr{sub 0.2}){sub 0.9}MnO{sub 3}-YSZ composite particles were synthesized by spray pyrolysis. The mean particle size of the synthesized powders was about 1 {micro}m and the particle size distribution was very narrow. The synthesized powders were composed of the perovskite (La,Sr)MnO{sub 3} and cubic phase YSZ. Each particle synthesized consisted of uniform and well-dispersed fine primary particles of (La,Sr)MnO{sub 3} and YSZ (0.1 {micro}m particle size).
