中文摘要
本論文主要開發不需變壓的可攜式被動式氫氣燃料電池,額定電壓5V,最大輸出功率可達10W,可應用於大部分市售3C產品所需的電源供應,最後開發的16-cell電池組串並聯以符合不同的3C產品的充電或是驅動。
研究內容分兩個階段:一﹒2-cell電池組特性研究,二﹒16-cell電池組特性研究與應用。由於質子交換膜燃料電池的操作能否穩定與質子交換膜內的含水量變動有相當的關係。本研究電池組在操作時,陰極完全曝露於大氣中,故水份很容易滲透蒸散到大氣,使交換膜缺水,故本電池組將設計一陽極加濕水槽,來補充電池組長時間操作下所蒸散的水份。本研究利用定電流量,測量電池在長時間操作下,電壓是否穩定。最後探討MEA不拆裝直接保存在stack中,保存方式對電池起動時穩定性與I-V性能的影響。
有了2-cell電池組量測的結果,接著將電池數目增加為16-cell進行量測與應用。本電池組藉由串並聯不同的電池數,可直接驅動或衝電手機、平板電腦及數位相框等10W以下3C產品。未來應可直接應用在各種不同的3C產品。
Abstract
In this thesis a portable passive hydrogen proton exchange membrane fuel cell (called PEMFC) stack is developed to drive or charge 3C products without any transformer. We divide our research into two stages. One is the characteristics study of a 2-cell PEMFC stack. The other is the characteristics studies and the applications of a 16-cell PEMFC stack. In the 2-cell stack, the effects of water content within proton electrode membrane on the performance of the stack are studied. In general, the cathode of MEA completely expose in the atmosphere so that the water is easily diffusing and evaporating into air. This phenomenon will cause water shortage and reduce the conductivity of proton within the membrane. Therefore, we add a water chamber within anode to supply water to make-up the evaporated water during long-period operation. The next, the effects of the storage methods of MEA on the stability and the performance are studied.
After studies of a 2-cell stack, we design and make a 16-cell stack. The rating voltage of this stack is 5 V. The maximum power output is about 10 W. The range of the power can drive or charge the most 3C products. The 16-cell stack can be series and/or parallel connected with different number of cells so that it can drive or charge a mobile phone, a pad, and a digital photo player without a transformer. The future commercial stack will directly drive or charge any 3C products with power less than 10 W.
