摘要

基于CFD(计算流体力学)对微型直接甲醇燃料电池(muDMFC)进行了建模和数值模拟，同时利用CFDRC商业规范研究了不同流道设计对muDMFC的影响。仿真结果表明，采用平行流场的muDMFC的性能优于采用点流场的muDMFC。实验结果表明，与仿真数据相比，具有平行流场的muDMFC在192.9mV电压下的最大功率密度为5.92mW/cm2，而具有点状流场的muDMFC在180.7mV电压下的最大功率密度为4.37mW/cm2。

The Effects of Different Flow Channels on Silicon-based Micro Direct Methanol Fuel Cells

Based on CFD (computational fluid dynamics), modeling and numerical simulation of the muDMFC (micro direct methanol fuel cell) are carried out ,meanwhile the influence of the muDMFC with various flow channels design is studied using the CFDRC commercial code. The simulation results show that the performance of the muDMFC with the parallel flow field excelled the one with the dot flow field. The experimental results show the same performance compared with the simulated data, and the muDMFC with parallel flow field has a maximum power density of 5.92mW/cm2 at the voltage of 192.9mV while the one with dot flow field has a maximum power density of 4.37mW/cm2 at the voltage of 180.7mV.
