固体氧化物燃料电池阳极材料的研究进展

Research progress of anode materials for solid oxide fuel cell

固体氧化物燃料电池(SOFC)因具有能量转换率高,燃料适应性强,环境友好和操作方便等优点,受到了人们的普遍关注,但是SOFC的广泛应用还有待于其关键材料的进一步发展。介绍了SOFC对阳极材料的基本要求,对阳极材料研究进展进行评述,重点对各种阳极材料(金属、YSZ金属陶瓷、Cu基金属陶瓷、Ce基氧化物以及钙钛矿氧化物等)性能方面的优缺点进行比较,并着重介绍了钙钛矿阳极材料(铬酸镧基氧化物)的进展情况,对改进阳极材料性能的各种措施进行了归纳和总结。

Solid oxide fuel cell （SOFC） as a power generation system has attracted much attention due to its many advantages in terms of high efficiency, fuel adaptability, low pollution and expediency operation. However, the application of SOFC requires research and development of its key component materials. The prospects and problems of the currently developed anode materials （metal, YSZ metal cermet, Cu-based metal cermet, Ce-based oxides and perovskite material and so on） of SOFC were elucidated. In particular, our recent study of perovskite material （LaCrO3-based oxide） was described. And some insight for the research and development of the anode materials for SOFC were offered.
