Synthesis and Characterisation of Mixed Conducting Perovskite Type Oxide and Its Electrochemical Application to Electrode Material for Solid Oxide Fuel Cell

Abstract

This article is concerned with synthesis, characteriducting perovskite type oxide to electrode materials for solid oxide fuel cell. First, this review provides a compre-hensive survey of the various synthetic methods such as solid state reaction, Pechini, glycine nitrate process and sol-gel methods for the preparation of perovskite type oxide powders. Subsequently, the electrical and microstructuralproperties of the mixed conducting oxides were discussed in detail. Finally, as electrochemical applications of themixed conducting perovskite type oxides to electrode materials for solid oxide fuel cell, fundamentals of theoreticalac-impedance model for porous mixed conducting electrodes iour of porous and dense mixed conducting electrodes prepared by various synthetic methods was discussed.
