| 中文摘要: |
| 研究在N2中利用直流扫描电压法、直流偏压法、交流阻抗谱法三种方法，分别测定了两类混合导电材料的电子电导率。研究发现，对于以电子导电为主的镧锶钴铁氧化物（LSCF）材料和以离子导电为主的LSCF与钐掺杂氧化铈（SDC）混合材料，该三种方法测量的结果在误差范围内都近似相同。说明此三种方法在测试混合导电材料的电子电导率上同样适用。 |
| 英文摘要: |
| Mixed ion-electron conductors(MIECs) are widely applied in various fields such as solid oxide fuel cells and lithium ion batteries.It is of great importance to accurately measure the electronic and ionic conductivities of MIECs,which provides us with deeper understanding of their applications.In this study,three different methods have been applied to measure the electronic conductivity of two types of MIECs in N2 atmosphere.It is found that the results of the three methods are almost equal in the error range,whether it is for LSCF with dominated electronic conductivity or LSCF-SDC material with dominated ionic conductivity.It indicates that the three methods are all available to measure the electronic conductivity of MIECs. |
