摘要

本研究，主要是利用套裝軟體ESI-CFD來分析質子交換膜燃料電池的單電池中流場、熱及電化學反應，藉由整個完整的模組建立，探討在不同電壓下電流密度的變化，並和實際的測量結果相互比對，希望能藉此評估模擬結果之準確率，以作為日後流場設計時的參考。

研究中單電池的反應面積為 與 兩種尺寸。 主要是用來驗證模擬和實作間的誤差藉此驗證模擬的可行性。 則是基於 之模擬結果與模型的建立參數，純粹以數位模擬的方式研究參數變動對性能之影響。這部分引用文獻中針對PEMFC實驗時所產生的現象作為模擬時的參數變更依據，例如流道分組、增加背壓，藉此了解模擬的結果是否與文獻相符，也藉此驗證本研究之模擬結果是否符合文獻所提之現象。

Abstract
This research mainly utilizes the ESI-CFD software to analyze the flow fields, heat and electrochemical reaction for a single cell within the proton exchange membrane fuel cell (PEMFC). Through creating the whole module, the changes of electrical current density under various voltages and make comparison with actually measured values can be explored. It is hoped that by using this evaluation, we can simulate the result accuracy available for subsequent reference for the design of flow fields can be simulated.
Within the research, the reaction areas of a single cell are and , on totally two kinds of dimensions. is mainly used to examine the error between simulation and experiment. Through this, it is available to examine the simulated plausibility. is the parameters created in accordance with the simulate result from model of . It is purely adopt the emulation ways to explore the possible performance influence caused by parameter changed. This part retrieves examples form some scientific literatures. It focuses on the phenomenon created by PEMFC experiment to serve as the reference for parameter changes under simulate, such as flow channel grouping arrangement and increasing back pressure. Through this, we can determine whether the simulate results well comply with those of past scientific literatures. Also, it is available to examine whether our results can comply with the existent trends
