中文摘要：

固体氧化物燃料电池（SOFC）具有高效、便捷、对环境友好和燃料适用性强等优点，被誉为21世纪的绿色能源．传统的SOFC采用YSZ作电解质，因其工作温度较高，带来一系列材料密封和结构设计上的问题．因此SOFC的中温化成为SOFC的发展趋势和研究热点，

英文摘要：

NiO-La0.3Ce0.7O2-δ （ LDC30 ） novel anode was investigated for IT-SOFCs （ Intermediate Tempera- ture-Solid Oxide Fuel Cells） with LaGaO3-based electrolyte. The results showed that LDC30 has a suitable chemical compatibility with NiO and NiO-LDC30 has a good thermal expansion matching with LDC30 interlayer and LSGM（ La0.8Sr0.2Ga0.8Mg0.2O3-δ） electrolyte, so NiO-LDC30/LDC30 was considered as a feasible and novel anode system. It was also shown that NiO content plays a key role on polarization performance and morphology of the anode. When the content of NiO was 60% （mass fraction）, the polarization loss of anode was the lowest. Next we will optimize the porosity and sintering procedure to modify the microstructure and performance of the anode.
