本論文主要開發可以攜帶並且可以長時間使用的氫氣燃料電池，除了滿足於市售3c電子產品所需的5V額定電壓之外，還需要注重是否可以永續利用。
研究分為兩個階段：一﹒2-cell電池組特性之研究，二﹒16-cell電池組之應用。燃料電池組是否能夠永續利用的關鍵之一便是MEA的性能存續，當MEA處於缺水狀態時，會由於質子交換膜過度乾燥而導致它產生顯著的收縮，進而跟電極產生剪應力的作用後產生剝離，因而降低了質子傳輸的能力並使得性能永久性的降低。故本電池組將會在陰極處配置棉線加濕裝置和簡單的封蓋來保持MEA在不操作時的含水量。本研究也調整了現有的陽極加濕裝置，並大幅增加了水分蒸散的面積，進而提高電池能夠穩定運作的最大電流密度。另外，為了減少導線損壞的機會，這次應用了感光電路板串聯來調整原有的導線纏繞式串聯。
當2-cell電池組取得了設計參數後，便會應用到8-cell電池組，並會針對3C產品進行驅動與充電實測。

This thesis is aimed to develop a set of PEMFC that can be operated stably for long-term use. The stacks can be applied to the recharging and operation of electronic devices.
Two stages are performed in present study. Firstly, the investigation of 2-cell stack stability, followed by the investigation of 8-cell stack stability and its application. The water content in the membrane is the key to maintain the performance of the fuel cell. To prevent the decay due to the lack of water content, we humidify the MEA using the cotton thread and cloth on the anode and cathode.
Under the moisturizing condition, 2-cell stacks can maintain the performance stability at current density 324 mA/cm2. When cells don’t function, the water content should be held constant to avoid the detachment of MEA on account of expansion and contraction of membrane. The water content transport through membrane is done by use of cathode threads, meanwhile excessive evaporation is segregated from the atmosphere. The result shows that MEA performance can be held effectively through the proper control over water content.
When applied to the 8-cell stack, similar results to 2-cell stack are yields for conserving. Nonetheless the maximal current density can only be kept under 300 mA/cm2 for stability. MEA area enlargement and the increase of formation heat are ascribed to the cause.
Lastly, when compared with AC adaptor to the supply mains, 8-cell stacks consumes more time to recharge. But this disadvantage can be overcome by adjusting the connection in series/parallel or the electrode area. The application of stacks in series/parallel connection is seen to be up-and-coming for future use of electronic devices.
