本研究使用微機電製程技術，製作出質子傳導奈米管道與燃料和氧化劑微米管道，再將晶片對位置入高溫爐完成熔融接合燃料電池微流體晶片，藉由奈米管道的電雙層重疊效應，使得帶有表面負電荷之奈米管道內部具有正(陽)離子選擇特性，以增益質子(氫離子)之電傳導率，取代以往的質子交換膜來進行質子傳遞的過程，本論文主要包含兩部分：(1)燃料和氧化劑流率影響功率密度分析、(2)奈米管道長度影響功率密度分析。
第一部份，由於燃料甲醇和氧化劑過錳酸鉀的流率和電池的性能有密切關係，本研究使用三種流率。探討不同的流率在相同的奈米管道長度下的燃料電池性能，並繪製電流密度與電壓曲線圖，並得最大輸出功率密度值，結果顯示出當燃料甲醇和氧化劑過錳酸鉀流率越大，而輸出功率密度則隨之上升。
第二部份，因為本文是利用奈米管道代替以往的質子交換膜進行質子傳導，所以本研究也改變奈米管道長短，探討電解質膜厚度(奈米管道)的影響，使用自行設計之三種奈米管道長度，結果顯示出奈米管道越短，電阻相對(歐姆阻抗)變小，電池功率密度越大。所以奈米管道在此種機制扮演著相當重要的角色。

In this study, proton exchange nanochannels and fuel/oxidant microchannels were integrated to form micro-direct methanol fuel cells (μ-DMFCs) using microelectromechanical system (MEMS) technology. The μ-DMFCs chip were designed, fabricated and tested. Two issues were investigated on the fuel cells performance: (1) effect of anode cathode flow rate and (2) effect of nanochannel length.
The flow rate of anode and cathode has importance effects on cell’s performances. We adopted three flow rates to investigate the fuel cell performance. The corresponding I–V performance curves are presented. The experimental results showed that better cell power density is obtained when the flow rate of anode and cathode increases.
Since this study used nanochannel to substitute former proton exchange membrane to process proton transport, the nanochannel length is resemblance to membrane thickness. Therefore, we used three nanochannel lengths, and sketched the corresponding I-V performance curves with different kinds of flow rate. The results show that when the nanochannel is shorter, the fuel cell power density is larger. Consequently, the nanochannel plays a very important role in μ-DMFC chip design and operations.
