中文摘要：

一个微直接甲醇燃料房间(DMFC ) 对在笔记本计算机，手机，和另外的数字产品的使用合适。在阳极流动隧道解决差的集体运输的效率问题，这份报纸与矩形的 convexes 论述一个 N-inputs-N-outputs 平行流动模式增强甲醇团运输和还原剂集中极化。模拟结果证明有矩形 convexes 的 N-inputs-N-outputs 平行流动隧道改进表演。DMFC，有四个阳极流动模式，用 MEMS (microelectromechanical 系统) 被制作技术。试验性的结果证明有矩形 convexes 的 DMFC 比以前报导的系统更好有表演，并且有 19.96 mW/cm2 的山峰电源密度。模拟和试验性的结果在好同意。

英文摘要：

A micro direct methanol fuel cell （μDMFC） is suitable for use in notebook computers, mobile phones, and other digital products. To resolve the poor mass-transport efficiency problem in the anode flow channel, this paper presents an N-inputs-N-outputs parallel flow pattern with rectangular convexes to reinforce methanol mass transport and reduce concentration polarization. The simulation results show that the N-inputs-N-outputs parallel flow channels with the rectangle convexes improve the performance. μDMFCs, which have four anode flow patterns, are fabricated using MEMS （microelectromechanical systems） technology. The experimental results show that the μDMFC with the rectangle convexes has a performance better than previously reported systems and has a peak power density of 19.96 mW/cm^2. The simulation and experimental results are in good agreement.
