Synthesis and Intermediate Temperature Electrical Properties of SrCe0.9 Yb0.1 O3-α-LiCl-KCl Composite Electrolyte
摘要
Abstract
Excellent protonic conductor of SrCe 0.9 Yb0.1 O3-αwas selected to compound with the LiCl-KCl. The heat-treated temperature ( 420 ℃) of SrCe0.9 Yb0.1 O3-α-LiCl-KCl is much lower than the conventional sintering temperature (1500 ℃) of SrCe0.9 Yb0.1 O3-α.X-ray diffraction pattern show that there has no reaction between SrCe 0.9 Yb0.1 O3-αand LiCl-KCl.The electrical conductivity of SCYb electrolyte and SCYb-LK composite electrolyte were investigated by electrochemical analyzer in various atmospheres between 400-600 ℃.The results display that the conductivity of the composite SCYb-LK electrolyte is 8.6 ×10 -2 S· cm-1 in the humid nitrogen atmosphere at 600 ℃, and the activation energy of the composite SCYb-LK electrolyte is much lower than that of the SCYb electrolyte .The H2/O2 fuel cell of SrCe0.9 Yb0.1 O3-α-LiCl-KCl generated the maximum power density of 113 mW· cm -2 at 600 ℃which is 7 times of SrCe0.9 Yb0.1 O3-αunder the same conditions at 700 ℃.关键词
