Abstract

La0.9Sr0.1Ga0.57Mn0.43O3 (LSGM) anode ceramics of solid oxide fuel cells produced using a reaction-sintering process were investigated. Without any calcination involved, the mixture of La2O3, SrCO3, Ga2O3 and MnO2 was pressed and sintered directly. Porous LSGM ceramics could be obtained at 1230-1270oC for 2 and 4 hours sintering. Temperatures higher than 1270oC are too high to obtain useful porous LSGM ceramics for 6 h soak time. A lower sintering temperature is needed in preparing LSGM ceramics using a reaction-sintering process than using the conventional solid oxide method. Reaction-sintering process has proven a simple and effective method in preparing LSGM ceramics for applications in solid oxide fuel cell anode.
