CHINESE ABSTRACT

什麼是燃料電池呢？如果你想要有關它的技術，燃料電池是一個電化學的能量轉換裝置，燃料電池把化學氣體氫和氧轉變成水，並且在過程中直接產生電，適用於各種小型的移動式的電源供應系統。
本文主要針對質子交換膜燃料電池（Proton Exchange Membrane Fuel Cell）組裝與性能比較，採用改良形式的筆直流道，探討電池其反應面積為14㎝ × 14㎝ 的單電池（Single Cell）。對單電池而言，探討其活化過程與活化過程後的整體參數的表現，包括不同的氣體加溼溫度及不同的氧化劑等。
最重要的是透過這些實驗與分析的一系列參數，這些結果將是影響PEM燃料電池特性的主要因素。對反應面積為14㎝ × 14㎝ 的單電池中，發現提升燃料氣體加溼溫度，可對於燃料電池的性能有明顯的提升。
若以空氣為氧化劑時，在觸媒表面的氧分子數量減少，因此降低了燃料電池的整體性能。實驗的結果呈現於極化曲線上，其顯示了PEM燃料電池於各種不同運作參數上的影響之性能。

ENGLISH ABSTRACT

What is a Fuel Cell？ If you want to know the technical information about it, a fuel cell is an electrochemical energy conversion device. A fuel cell converts the chemicals hydrogen and oxygen into water, and during the process it produces electricity, so it is suitable for every kind of small mobile power device.
The object of this thesis is to fabricate and compare the perform of proton exchange membrane fuel cell. The flow field used reformation flow field type where the active area of the membrane is 14cm×14cm single cell. The effects of different operating parameters on the performance of proton exchange membrane fuel cell have been studied experimentally using pure hydrogen on the anode side and pure oxygen or air on the cathode side. Experiments with different cathode and anode humidification temperatures, different oxidant of these parameters have been carried out.
Above all, the experiment and analysis of a serial of parameter through, the result shall be the key factor which be carried and affect the characteristics of PEM fuel cell.In the single cell with 14cm x 14cm active area, to improve fuel gas of humidification temperature can promote obviously performance of the fuel cell. From the experiment results, the performance of oxygen type module is better than that of air type, because the oxygen content is less in the air type. The experimental results are presented in the form of polarization curves, which show the effects of the various operating parameters on the performance of the PEM fuel cell.
