| 摘 要： | 采用高温固相法制备了La0.75Sr0.25Cr0.5Mn0.5O3(LSCM)并利用XRD,SEM以及电化学阻抗谱(EIS)分别对粉体及电极进行研究。结果发现LSCM在C3H8-O2-N2混合气氛下能够保持很好的高温化学稳定性,且与电解质材料YSZ在1400℃空气气氛下不发生化学反应。电化学测试结果表明,阳极支撑型单室固体氧化物燃料电池Ni-YSZ|YSZ|LSCM在700℃、C3H8-O2-N2混合气氛下的短路电流密度达317 mA·cm-2,最大功率密度73 mW·cm-2。将LSCM与CGO形成梯度阴极,相同测试条件下,单室电池的短路电流密度为560 mA·cm-2,功率密度达到110 mW·cm-2,电池输出性能提高约50%。

| Abstract: | La0.75Sr0.25Cr0.5Mn0.5O3(LSCM) was prepared by Solid State Reaction and studied by XRD,SEM and EIS spectrum,respectively.The results showed that LSCM maintains good chemical stability at high temperature in the reduced C3H8-O2-N2 atmosphere.This material has no reaction with YSZ at 1 400 ℃ in air.The short-circuit current density of the anode supported single chamber solid oxide fuel cell(SC-SOFC) Ni-YSZ|YSZ|LSCM reached 317 mA·cm-2 and the maximum power density was 73 mW·cm-2 at 700 ℃ in C3H8-O2-N2 mixed atmosphere.In the gradient cathode SC-SOFC,a short circuit current density of 560 mA·cm-2 and the power density 110 mW·cm-2 was obtained in the same test condition.In this way,the output performance of the cell increased by about 50%. |
