本論文主要研製可直接作為3C產品電源或充電的可攜式氫燃料PEMFC電池組。為了可攜式的應用，故儘量簡化電池組結構，並採用air-breathing及室溫下操作。研發出的雙層16-cell電池組，共使用32條碳纖維束，而每條碳纖維束皆可形成一獨立電流蒐集器，搭配兩組8-cell Banded-type MEA，在電池組外部可8 cell或16 cell串聯，很容易形成所需的較高電壓。
本電池組的每條碳纖維束組裝前，皆與碳布結合並進行電阻量測。在結合壓力3bar或以上，每條碳纖維束單極板與碳布結合後的總電阻可降到8.7 mΩ或11 mΩ•cm2以下，為石墨單極板與碳布結合後總電阻的1/2。碳纖維束的良好透氣性，也可使電池組能於自然吸氣下，便具備良好的操作性能。此外，外部串聯將使用集線電路板，解決導線零亂的缺點，使整體電池組更加美觀且容易裝卸。
本論文研發出的16-cell氫燃料電池組，長9.6cm、寬6.3cm、厚2.2cm，電極總面積50.4cm2。在air-breathing及室溫下操作，8-cell時，輸出電壓3.7V時，總功率可達3.6W，可直接用於3.7V的PDA、手機或數位相機。16-cell時，輸出電壓7.2V時，總功率可達7W，可直接應用於7.2V的數位單眼相機。若使用2或多個電池組串聯時，則可應用到筆記型電腦等須更大功率產品的操作或充電。

In this thesis, a portable PEMFC stack, which can directly power or charge 3C products, will be developed. The stack is developed for portable applications, so the structure of the stack is simplified as possible as we can. The PEMFC stack is made with 32 carbon fiber bunches for current collectors and two 8-cell banded-type MEAs which are made with 8 sets of electrodes on a piece of membrane. The stack can develop a high voltage by serially connecting 8 cell or 16 cell outside of the reaction chamber.
The resistance of each carbon bunch assembling with carbon cloth is measured before they are assembled into the stack. Under assembly pressure 3 bar, the total resistance is about 8.7mΩ or 11mΩ•cm2. The resistance is about one half of that graphite plate assembling with carbon cloth. Without being compressed greatly in diffusion layer, the fluid can easily flow through the gaps between carbon fiber and within diffusion layers, and then the reactive region will react more uniformly. In addition, the connecting wires are assembled to a wire collecting board, so that the stack is look more neat, and it easier assemble or dissemble.
In this thesis, the volume of the developed 16-cell hydrogen fuel cell stack is about 9.6 cm*6.3 cm*2.2 cm. The total electrode area is 50 cm2 (16-cell×3.15 cm2 per cell). When the stack is operating at room temperature and air-breathing, an 8-cell stack in series connection can generate 3.7V voltage. Its power at voltage 3.7V is about 3.6W. It can directly power PDAs, mobile phones or digital cameras. A 16-cell stack in series connection can generate 7.2V voltage. Its power at this voltage can offer 7W. The 16-cell stack can directly power digital single-lens reflex cameras. If two or more of this stack are connected in series, it will be able to power a notebook or other more power products.
