摘　　要：为了改善固体氧化物燃料电池(Solid Oxide Fuel Cell,SOFC)的性能,本文提出了一种具有球状结构的新型流道,并与传统结构进行了对比。结果表明,与基本直流道相比,带有挡板流道的SOFC和带有球状结构的SOFC电流密度分别增加了6.42%和7.14%,总压降分别增加了3.63倍和2.15倍。由此可知,具有球状结构的新型流道具有更好的综合性能优势。To enhance the performance of Solid Oxide Fuel Cells(SOFCs),a new flow channel with spherical obstacles is proposed and compared with traditional designs.It is concluded that compared with the basic straight channel,the current density of SOFC with rectangular baffles and SOFC with spherical obstacles increases by 6.42%and 7.14%,and the total pressure drop increases by 3.62 times and 2.16 times,respectively.It is thus evident that the new SOFC design proposed in this paper can be used for better overall performance.
