The model in this work is based on control volume analysis and can easily be used to set up different operational strategies. Two specific situations were studies: in the first scenario, the fuel cell and high pressure vessel were thermally coupled; in the second scenario, the high pressure vessel and a radiator were thermally coupled. The system efficiency and dynamic behavior of these two strategies will be clearly compared. Besides, in order to establish a 5kW PEMFC stack, a two cells stack with 196cm2 reactive area was assembled and tested for further designing.目錄 致謝.....................................................Ⅰ 摘要.....................................................Ⅱ 英文摘要.................................................Ⅲ 目錄.....................................................Ⅳ 圖目錄...................................................Ⅶ 表目錄...................................................Ⅸ 符號說明.................................................Ⅹ 第一章 緒論..............................................1. 1.1 前言...............................................1. 1.2 研究目的...........................................2. 1.3 研究方法...........................................2. 1.4 論文大綱...........................................3. 第二章 理論分析..........................................5. 2.1 系統界定及理論架構.................................5. 2.2 系統元件模擬.......................................6. 2.2.1 高壓儲氫瓶.....................................6. 2.2.2 壓力控制閥.....................................8. 2.2.3 熱交換器.......................................9. 2.2.4 加溼器........................................10. 2.2.5 燃料電池組....................................11. 2.3 系統模擬..........................................15. 2.3.1 阻力係數與質量流率............................15. 2.3.2 高壓氣瓶的溫度與壓力..........................16. 2.3.3 模擬流程......................................18. 2.4 結果與討論........................................22. 2.4.1 冷卻水加溫高壓氣瓶............................24. 2.4.2 電熱片加溫高壓氣瓶............................35. 2.4.3 系統效率及暫態比較............................43. 第三章 實驗設備.........................................50. 3.1 燃料電池組........................................50. 3.2 系統設備..........................................54. 第四章 電池組性能測試實驗...............................57. 4.1 實驗規劃..........................................57. 4.2 電池效能測試......................................57. 4.2.1 單一電池測試..................................57. 4.2.2 電池組效能測試................................63. 第五章 結論及未來研究方向...............................65. 參考文獻................................................68.3711678 bytesapplication/pdfen-US質子交換膜燃料電池系統模擬動態模擬設計PEM fuel cellsystem simulationdynamic simulationthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/61620/1/ntu-94-R92522304-1.pdf
