摘要

本論文主要在開發一個能穩定操作,不須變壓的可攜式直接甲醇燃料電池,簡稱DMFC。本研究的燃料補充裝置採用被動的方式,不需任何加壓裝置因此可減少電池組的總體積及減少能量的消耗。為了避免長時間操作時,被動式DMFC反應室內的甲醇溶液水位及濃度降低,使性能下降,設計了一套在不同電流下可連續穩定補充燃料的裝置,能使反應室裡甲醇溶液水位及濃度維持在適當範圍。
為了能對3C產品進行直接充電,開發了一組16-cell電池組電壓5V,電流300mA,此電池組不須變壓能對一些小功率的3C產品直接充電或驅動。實驗已驗證,此電池的燃料補充裝置能穩定補充燃料,可使電壓穩定操作3小時後,反應室內甲醇溶液濃度仍維持在初始濃度2M附近。此DMFC電池組也已成功應用到智慧型手機、MP3及隨身收音機等產品的充電,預計未來將可作為各種3C產品的直接驅動或充電電源。

Abstract
Abstract

A portable direct methanol fuel cell (called DMFC) stack without a transformer, which can operate steadily, is developed in this thesis. The fuel supplemental device is passive and without any compressive instrument so that the total volume and the power consumption can be reduced. In order to avoid the decrease of the level of methanol solution and its concentration in the reaction chamber, a fuel supplemental device of a DMFC stack is designed for a long-time operation steadily under various current conditions.
In order to charge 3C products directly, a 16-cell DMFC stack with about 5V and 300 mA is designed and fabricated. The stack can directly charge or drive these small power 3C products without a transformer. The experimental results show that the fuel supply device of the DMFC stack can feed fuel steadily. Therefore, the concentration of methanol solution within the reaction chamber remains the same as the initial value about 2M. The stack is already success to be used in the charge of an intelligent mobile phone, a MP3 player, and a portable radio. We expect that the stacks can be used as energy sources to drive or charge various 3C products.
