摘要/Abstract

摘要： 采用离心沉降法及高温共烧结工艺在多孔NiO-Sm_0.2Ce_0.8O_1.9(SDC)阳极上成功地制备了SDC/LSGM (La_0.9Sr_0.1Ga_0.8Mg_0.2O_3-δ)/SDC电解质薄膜. 经共烧结制备了11μmSDC/15μmLSGM/13μmSDC三层复合电解质薄膜. 电池在800℃最大输出功率密度为0.92W/cm², 但电池的开路电压0.89V低于理论电动势. 电池微结构和元素分析表明, 高温共烧结时Ni扩散到LSGM电解质薄膜中引起电子电导, 导致电池开路电压偏低. 阻抗谱测试表明, 引入SDC电解质作为隔离层后, 欧姆极化过程和电极极化过程共同影响电池的性能

Abstract: Anode-supported solid oxide fuel cells (SOFCs) composed of NiO-SDC (Sm_0.2Ce_0.8O_1.9) composite anode, thin tri-layer electrolyte, and La_0.6Sr_0.4Co_0.8Fe_0.2O₃ (LSCF)-La_0.9Sr_0.1Ga_0.8Mg_0.2O_3-δ (LSGM) composite cathode were fabricated. The thin 11μmSDC/15μmLSGM/13μmSDC tri-layer electrolyte was prepared by centrifugal casting and co-firing technique. Cell tests in air as oxidant and humidified hydrogen as fuel show a maximum power density of 0.92W/cm² at 800℃. However, the open-circuit voltage (OCV) of these cells is 0.89V which is lower than the Nernst potential. The above result is due to electronic conductivity in the LSGM layer, resulting from Ni impurities that entered during co-firing with the NiO-SDC anode. While the SDC buffer layers are introduced as buffer layers, impedance measurements indicate that both the ohmic resistance and the polarization resistance dominate the cell performance.

Key words: solid oxide fuel cells, La_0.9Sr_0.1Ga_0.8Mg_0.2O_3-δ, Sm_0.2Ce_0.8O_1.9, performance
