Sol-gel法合成La0.9Sr0.1Ga0.8Mg0.2O3-δ电解质及其电池性能研究
Performance of SOFC with LSGM electrolyte synthesized by sol-gel method
摘要
Abstract
La0.9Sr0.1Ga0.8Mg0.2O3-δ (LSGM) powder was prepared by sol-get method. DSC-TGA and XRD indicate that the pure perovskrte phase of LSGM is obtained after calcined in air at a temperature of 1 250 ℃ for 3 h. EOX confirmed the powder has no impurity element SEM and laser size distribution analysis show that the average size of the powder is 0.9 μm. The current-voltage curve and electrochemical impedance spectra (EIS) for the single SOFC with Ni/GDC (Ce0.9Gd0.1O1.95) anode, LSCM/GDC cathode and LSGM electrolyte was examined. SEM suggest that the LSGM film of about 37μm thick is well adhered to the anode. The cell produced a maximum power density of 0.89 W/cm2 at 800 ℃ and the open circuit voltage of the cells were all above 1.0 V. The cell performance indicates that LSGM synthesized by the sol-gel method can be applied to the electrolyte of SOFC.关键词
