摘 要
近幾年來由於電腦科技與通訊技術進步快速，可攜帶式電化產品以顯著倍數增加，因此要求時間長與高性能之電池已是現今世界發展之趨勢，而PEM型燃料電池將是達到此種條件最有效之電力源。本次實驗主要是以質子交換膜燃料電池單電池組為基礎，純氫、氧為燃料，進氣時以乾燃料與加濕燃料之條件下對電池內之溫度、壓力及氣體流量作一系列規律之實驗，測試反應性能並將此結果分析、比較探討其相互關係。討論分析結果發現乾燃料進入電池後直接影響MEA之濕度比，在此條件下性能操作，以電池濕度控制為首要條件。因此在單一參數因子以流量影響最大，溫度次之；兩參數因子相互作用時，以溫度—流量影響最大；加濕燃料時單一參數因子則以溫度參數因子影響最大。因此以適當之進氣流量與溫度控制濕度比成為影響發電效率之最大關鍵因素。

ABSTRACT
Recently, the requirements for technology of computers and communications have increased dramatically. A portable electric power supply with long duration and high performance is then needed for these products. A proton exchange membrane fuel cell (PEMFC) can meet these requirements and becomes one of the best candidates as the portable power source. But limited by the products volume, the existing portable fuel cell has to control its humidity to reach an optimized performance of the application region. This paper is therefore to present a series of experiments to investigate the performance of a single PEMFC. The pure hydrogen and oxygen are used for fuel. The effects of different operating conditions about dry and humidified fuel on the cell performance are also discussed, which include the temperature, pressure, and inlet fuel flow rate. These experimental results can provide useful information for investigating the cell performance. The results of discussion and analyses indicate MEA humidity ratio is influenced by dry flow into cell directly. Operating as this condition, it is the most important condition in cell is humidity control. So, at single parameter, the most effect is flow, temperture next; two parameters interaction each other, the most effect is temperture-flow; at humidified fuel condition, at single parameter, the most effect is temperture. Therefore, it is very important factor of influencing the performance is caculating flow and temperature exactly to control humidity ratio.
