摘要

运用计算流体力学软件COMSOL

建立了微型直接甲醇燃料电池（μDMFC）三维数值模型

并用MEMS工艺制作电池进行实验验证。模型耦合了连续性方程、电化学反应方程和动量方程等。通过对模型求解

输出了平均电流密度和电压等参数。分析了扩散层和催化层结构参数对电池性能的影响

结果表明:过厚的催化层对电池性能提升并无太大帮助

在增大电催化剂Pt担量前提下应尽量减小催化层厚度。

Abstract

A three-dimensional model of micro direct methanol fuel cell（ μDMFC） is presented based on the computational fluid dynamics software COMSOL

. It is validated by experiments with MEMS craft. The controlequation of the method is a coupling of continuity equation

momentum equation and electrochemical reaction equations. The performance of the μDMFC is investigated by calculation of the three-dimensional model. The analysis on diffusion layer and catalytic layer show that too thick catalytic layer isn’t beneficial for improvement of performance of μDMFC. On premise of increased load of Pt catalyst

it’s better to decrease thickness of catalyst layer.
