摘要: | 本研究旨在建立質子交換膜燃料電池(PEMFC)電堆模型,有別過去大多使用複雜有限元素模型之方法,改以代數方程式進行電堆性質描述,並以系統參數反應不斷累加的方式來得到燃料電池動態模擬結果,減少系統模擬時間。本研究可提供質子交換膜燃料電池系統開發者與實驗者,快速預測燃料電池的性能表現,縮短系統開發與實驗的時間。本研究使用美國MathWork公司所研發的MATLAB /Simulink軟體,作為此質子交換膜燃料電池電堆模型之開發工具。
本研究將質子交換膜燃料電池(PEMFC)電堆依據其物理特性,劃分為大模型區塊,包含電氣特性模型、溫度及熱傳特性模型、質傳特性模型,並且把參數分為外部參數、燃料電池系統特性參數、系統變動參數。分別針對此三大模型區塊,撰寫MATLAB/Simulink程式,建立模型程式與驗證模型的準確性。最後把三大模型加以整合,完成質子交換膜燃料電池電堆模型開發,並且使用不同輸入參數,分析本模型的計算結果,用來預測燃料電池的性能表現。 This research is for the purpose of establishing the proton exchange membrane fuel cell (PEMFC) stack model. And the model in this study will be described by the algebraic equation which is different from complex finite element method. The system parameters are accumulated unceasingly to obtain the fuel cell dynamic simulation result and the model can reduce the simulation time. Moreover, this research provides for the PEMFC system developers and experimenters to calculate the performance of the fuel cell and reduce developmental and the experimental time. Besides, we use the MATLAB/Simulink software which is developed by American MathWork Corporation as development kit of PEMFC stack model. According to their physical properties, this research divides PEMFC stack model into three main programs. They contain electrical model, heat transfer model and mass transfer model, and also divide parameters into external parameters, fuel cell stack parameters and dynamic parameters. We program MATLAB/Simulink codes separately for the three models and then confirm the model exactitude. Last but not least, the three models will be combined to form PEMFC stack model, which is used to analysis fuel cell performance with the different input parameters. |
