新型复合阴极Sr0.95Ti0.05Co0.95O3?δ–Sm0.2Ce0.8O1.9 在中低温固体氧化物燃料电池中的性能
DOI: 10.14062/j.issn.0454-5648.2015.07.02
Abstract:
采用柠檬酸自蔓延燃烧法合成了Sr0.95Ti0.05Co0.95O3？δ(STC)阴极粉体和Sm0.2Ce0.8O1.9(SDC)电解质粉体,将STC与SDC粉体按质量比73混合得到复合阴极。通过X射线衍射(XRD)、直流四端子法和热膨胀仪表征了样品的化学相容性、电导率和热膨胀系数。XRD表明，STC在900℃能够得到立方纯钙钛矿结构，复合阴极STC？SDC在工作温度区间内具有很好的化学相容性；在650℃空气气氛下STC？SDC与SDC之间的界面极化阻抗仅为0.05Ω?cm2。制备了阳极支持型(NiO-SDC│SDC│STC？SDC)单电池,在450～650℃范围内以湿润的H2(3%水蒸汽)为燃料气，空气为氧化剂测试了单电池的性能。结果表明阳极支撑的单电池共烧1350℃可以得到致密的电解质层和多孔的电极,而且650℃时单电池开路电压0.82V，最大输出功率为721mW/cm2。结果预示，在以SDC为电解质的中低温固体氧化物燃料电池(IT-SOFC)中，STC-SDC是一个很有前途的复合阴极材料。
