本文的主要目的為探討如何藉由改變陰極空氣供給方式,提升所設計出圓盤式直接甲醇燃料電池的效能。研究中陰極空氣供給來源分別為軸流扇與空氣幫泵,電池的陰極空氣阻抗由依據AMCA 210規範之風洞量測,電池整的平均cell 效能與個別量測cell 所得之效能將互相比較。本研究使用的MEA有效面積為35mm x 35mm,未來可依需求採用不同大小的MEA 加以排列,做出更廣泛的應用。 The main objective of this paper is to discuss how to increase the developed disc type direct methanol fuel cell (DMFC) by changing the cathode air supply way. In the research, the cathode air was supplied by the axial fan and air pump. The airflow resistance was obtained by a AMCA 210 wind tunnel. The average DMFC cell performance was compared with the individual measured cell performance. The effect area of the MEAs adopted in the research is 35mm x 35mm. In the future, the DMFC can be designed via arrayed MEAs with different size and make more applications.
