초록

Nowadays perovskite $La_{1-x}Sr_xMnO_3$ is preferred cathode material in Solid Oxide Fuel cell(SOFC). The $La_{1-x}Sr_xMnO_3$ with Sr contents ranging $x=0{\sim}1.0$ were prepared by a citrate method. These powders were characterized by usual means like TG/DTA, X-ray diffraction analysis. 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 by-product of $La_{1-x}Sr_xMnO_3$ reacted with 8mol% YSZ, that samples were sintered at $1200^{\circ}C$ for 5 hours.
