【摘要】 研究了熔融碳酸盐燃料电池(MCFC)阴极材料锂铁氧化物电极的导电性能.实验结果表明在合成锂铁氧化物的过程中,使Li2CO3轻微过量,可以提高锂铁氧化物电极的导电性.在同一温度下,随着Li:Fe值的增大,锂铁氧化物电极的导电性增加.相同Li:Fe条件下,锂铁氧化物电极的导电性随着温度升高按指数规律增加.扫描电镜研究(SEM)表明,Li:Fe比值不同,制备的锂铁氧化物电极表面形貌也不同.更多还原

【Abstract】 The conductivity performance of lithium fertile oxide for molten carbonate fuel cells was investigated. The results showed that the conductivity of lithium fertile oxide can be improved by making Li2CO3 excessive slightly in the prcess of preparing lithium ferrite oxide. At the same temperature, the conductivity of lithium ferrite oxide increase with the increasing of Li:Fe values. However, at the same Li:Fe value, the conductivity of lithium ferrite oxide increases exponentially with the increasing of temperature. SEM analysis showed electrode surface micrographics of lithium ferrite oxide with various Li:Fe values are different.更多还原
