碩士 === 國立臺北科技大學 === 資源工程研究所 === 102 === In the gradual depletion of energy background, green energy increasing attention, wherein the solid oxide fuel cell (SOFC) is great potential for green energy technology. The traditional SOFC cathode material (LSM) and electrolyte (YSZ) material at high temperatures with high conductivity, high catalytic activity and thermal stability, but the high temperature limit of the material properties of the work environment. However, as the temperature decreases, the ion conductivity of the cathode material is also reduced, increasing the impedance of the cathode and the electrolyte. The main way to reduce the cathode impedance using the ion electron mixed conductors such La0.6Sr0.4Co0.2Fe0.8O3-δ, or the use of composite cathode electrolyte / cathode, etc.In this study we use succeed to synthesize a novel SOFC eight element composite cathode by Glycine-Nitrate process ( LaSrBaSmFeMnCoCuO3-δ/Gd-Sm-CeO2-δ), Analysis by Taguchi, Obtain the best crystal phase purity and conductivity of perovskite / fluorite structure SOFC composite cathode material.
