摘要

微型直接甲醇燃料电池中阳极流场结构对电池的性能有着重要的影响。为了合理设计阳极流场结构

改善甲醇燃料在阳极流场中的分布

采用计算流体动力学（CFD）软件Fluent对微型直接甲醇燃料电池进行建模并仿真分析。分析比较了点型、平行和蛇形3种不同流场图案下得到的压降与流速分布

得出蛇形流场能够更有利于甲醇燃料的均匀分配。在此基础上分别建立不同流道宽度（800

400

200

100μm）的蛇形流场模型

通过仿真计算甲醇燃料的分布情况来分析其对燃料电池性能的影响

并结合实验结果进行对比得出流道宽度为200～400μm之间为优化值。

Abstract

Structure of anode flow field is very important for micro direct methanol fuel cell.To optimize the structure of the anode flow field and the distribution of methanol in it

a model of micro direct methanol fuel cell is created and analyzed by using the computational fluid dynamics（CFD） software.The influence of flow field shapes of grid

parallel and serpentine are analyzed and the pressure drop and velocity distribution in the three kinds of flow fields are studied.It shows that the flow field of serpentine is the best for the even distribution of fuel.Based on this

serpentine flow field models with different width（800

400

200 and 100 μm） are created.Simulations are taken to analyze the influence of distribution to cell perf

ormance and compared with experimental results

it shows that the optimal value of flow channel width is 200

00 μm.
