La 0.8 Sr 0.3 MnO 3 (LSM)/Y 2 O 3 stabilized ZrO 2 (YSZ) composite powders were mechanically prepared. By changing the mechanical device or processing time, three composite powders with different size distributions were obtained. Then the powders were formed into cathodes of solid oxide fuel cells (...
