    Abstract: 本論文主要目的為設計不同流道,探討直接甲醇燃料電池在不同陰陽極流道板組合下,對其電池效能影響為何。在研究過程中,設計三種蛇行流道,及二種平行式流道,其中二種蛇行流道及一種平行式流道為波浪型流道。對直接甲醇燃料電池在不同陰陽極流道板組合下進行電池效能量測,比較在不同流道板的情況下,對直接甲醇燃料電池效能的影響,並觀察將波浪型流道對電池效能有無影響,接著對陽極流道氣泡排除現象進行量測,以及對電池進行電化學阻抗分析。研究結果顯示,將流道更改為波浪型流道對燃料電池效能有所提升。
    The main purpose of this thesis is to investigate the different flow channel design effects on direct methanol fuel cell (DMFC) performance. Three serpentine type flow channels and two parallel type flow channels are fabricated and discussed. The three serpentine flow channels include the general serpentine type, the unilateral crooked serpentine type and the double-lateral crooked serpentine type. The two parallel flow channels include the general parallel type and the double-lateral crooked parallel type. Experimental investigations into the DMFC polarization curves, CO2 bubble dynamics in anode flow channels and the electrochemical impedance spectroscopy with different flow channel combinations are conducted. Results of this study show that the double-lateral crooked flow channels can improve the DMFC performance.
