摘要
研究不同结构设计条件下,活化极化、欧姆极化、浓差极化对SOFC性能的影响。在分析浓差极化时,综 合考虑了普通扩散和Knudsen扩散,使模型更接近实际。采用灵敏度分析方法,分析了5个结构参数对SOFC性能 的影响。结果表明,在该文的分析条件下,阳极支撑的设计具有较好的输出特性。
The effects of activation, ohmic and concentration polarization on the overall performance of SOFC were studied under different designs. Both ordinary and Knudsen diffusions were considered. The effects of the pore size, porosity and tortuosity on the model predictions were also discussed in details. Sensitivity analysis has been performed to exam the effect of the parameters on the power density of SOFC. The result showed that the anode-supported cells have a better output performance than other designs.
