Abstract

Nowadays Perovskite $La_{1-x}Sr_xCoO_3$ is a preferred cathode material in the construction Solid Oxide Fuel Cell (SOFC). The $La_{1-x}Sr_xCoO_3$ with Sr contents ranging from X=0.0 to X=1.0 were prepared by a citrate method. All samples were examined by X-ray powder diffraction. The samples used for measuring thermal expansion were prepared as pellets by cold pressing and subsequent sintering in air at $1200^{\circ}C$ for 5 hours. To measure the sub-product of $La_{1-x}Sr_xCoO_3$ with YSZ, where coating films were sintered at $1200^{\circ}C$ for 5 hour.
