摘要： 制备了阳极负载型LDC-LSGM双层电解质薄膜电池.考察了单电池在分别使用甲醇和氢气两种燃料时,不同温度下的I～V性能.以甲醇为燃料,以空气为氧化剂时,800℃下的最大输出功率密度为1.07W/cm2,而使用氢气为燃料时,最大输出功率密度为1.54W/cm2.通过交流阻抗研究了造成甲醇性能降低的可能原因.结果表明,以甲醇作为燃料时,单电池性能较氢气作为燃料时低.

Abstract: Anode-supported solid oxide fuel cell with LDC-LSGM bilayer electrolytes and GDC+NiO anode substrate was fabricated and operated by using H2 and methanol as the fuels respectively at temperatures from 650 to 800 ℃. At 800 ℃, the single cell exhibits the maximum output power density of 1.54 W/cm2 with H2 as the fuel and that of 1.07 W/cm2 with methanol as the fuel. The impedance spectra of the single cell show some differences when the two different fuels are respectively used, and the anode activity towards methanol is the key factor for the cell performance.

Key words: IT-SOFC, Anode-supported type, Bilayer electrolytes film, Direct-methanol oxidation
