新型电解质材料CaZr0.1Ti0.9O3的制备与电性能
摘要:
采用溶胶-燃烧法合成了可用于固体氧化物燃料电池(SOFC)的新型固体电解质材料CaZr0.1Ti0.9O3。通过XRD、交流复阻抗等电化学方法对样品的结构、电导性能进行了表征,并考察了材料的烧结性能。结果表明,溶胶-燃烧法可以成功制备出具有良好烧结性能的CaZr0.1Ti0.9O3电解质粉末,1 400℃下得到的烧结体的相对密度可达到95%。电性能测试表明,CaZr0.1Ti0.9O3烧结体在中温范围内具有较高的氧离子电导率(σ800℃=2.24×10-3S/cm)、低的电导活化能(0.89 eV)。

Preparation and Electrical Property of Novel Electrolyte Material CaZr0.1Ti0.9O3
Abstract:
A novel electrolyte CaZr0.1Ti0.9O3 for solid oxide fuel cell(SOFC) was synthesized by a newly sol-combustion method.The structure and conduction properties of the sample were systematically investigated via XRD and electrochemical methods.The results show that CaZr0.1Ti0.9O3 powders were successfully prepared by the sol-combustion technique.The powder shows a high sinterability,and a relative density of 95% at a sintering temperature of 1 400 ℃.Electrochemistry measurements show that the CaZr0.1Ti0.9O3 ceramics has a relatively high oxide ionic conductivity(σ800 ℃=2.24×10-3 S/cm),low electrical activation energy(Ea=0.89 eV) in the low-temperature range.
