本文旨在探討環烯烴共聚物摻合陽離子型光起始劑的混摻薄膜在直接甲醇燃料電池的工作環境下之適用性。實驗上經由抗張試驗去分析混摻薄膜的力學性質，發現其應力應變均隨著光起始劑比例提高而降低。使用掃描式電子顯微鏡進行型態觀察及元素分析，發現光照後其碘，硫，氟元素比例均提高，但經過水洗之後元素比例均大幅降低。使用熱重損失分析儀去觀察混摻薄膜的熱裂解過程，得知混摻膜材的熱裂解溫度高達460℃，光起始劑的熱裂解溫度為250℃，故此混摻膜材具足夠熱穩定性在直接甲醇燃料電池系統中使用。在導電率與含水率方面使用交流阻抗儀測試得知兩項性質均隨著光起始劑添加比例的增加而提升，了解到光起始劑可以幫助提升質子傳輸性質。且光照後的試片其導電率與含水率都高於光照前的試片。甲醇滲透方面，依據ASTM的E96規範使用水蒸氣滲透測試方法測量膜材對甲醇水溶液蒸氣的擴散程度。另一方面將實驗完的甲醇水溶液利用Abbe屈折度儀測量其濃度差異，藉此了解膜材對甲醇分子阻擋的能力。得知甲醇蒸氣滲透率隨著光起始劑比例的提升而降低，且實驗後甲醇水溶液的濃度隨著光起始劑比例的提高而增加，代表光起始劑比例越高的試片其阻擋甲醇分子的能力越佳。且無論是阻擋甲醇水蒸氣或是甲醇分子的能力，光照後的試片均優於光照前的試片。

This paper explores the applicability of blended cyclo olefin copolymer films containing doping cationic photo initiator in the direct methanol fuel cell operating environment. Experimental tensile strength measurements were used to analyze the dynamic properties of the films, and yielded the finding that dynamic response fell with increasing concentration of photo initiator. A scanning electron microscope was used to perform state observations and elemental analysis; it was found that the ratios of the elements iodine, sulfur, and fluorine increased after illumination, but decreased sharply after water washing. A thermo gravimetric analyzer was used to observe the thermal decomposition process of blended films, and revealed that the decomposition temperature of the film was as high as 460°C, while the photo initiator had a decomposition temperature of 250°C. This indicates that blended films have sufficient thermal stable for use in direct methanol fuel cell systems. Use of an AC resistance meter revealed that both conductance and moisture content increased as photo initiator was added. This shows that addition of a photo initiator can help increase proton transmission properties. The conductance and moisture content of a test plate also both increased after illumination. As for methanol permeability, the ASTM E96 steam permeability test method was used to measure the diffusion of fumes from a methanol-water solution in the film. In addition, an Abbe refractometer was used to measure the concentration of the methanol-water solution used in the previous experiment and gain a better understanding of the film's ability to block methanol molecules. It was found that the diffusion of methanol-containing steam decreases with increasing photo initiator concentration, and also shown that the concentration of the methanol-water solution remaining after the experiment increases with photo initiator concentration. It was revealed that test plates with high photo initiator concentration have good ability to block methanol molecules. Finally, test plates were uniformly better able to block both methanol molecules and steam containing methanol after illumination.
