本研究是使用金屬雙極板與金屬發泡材,組成質子交換膜燃料電池之單電池,且搭配商用膜組,探討雙極板不同入出口流道氣體分佈設計,於反應物流量、操作溫度、加濕溫度等,對電池性能之影響。
金屬板導電性能佳、機械性能強度好,適合作為雙極板的材料;使用金屬發泡材取代傳統內流道的作法,在單電池上已被證實有傑出的性能。本研究目的即是在觀察,不同雙極板入出口流道氣體分佈應用在單電池時,其性能表現與運作特徵;同時探討入出口氣體分佈均勻度所造成性能的影響。
由實驗結果可知,使用雙極板入出口流道氣體均勻分佈設計,對於電池性能有顯著的增加;入出口流道氣體均勻分佈設計對於性能的影響,較改變電池溫度與加濕溫度,更有助於電池性能的提昇,對於後續金屬發泡材燃料電池研究開發有著很大的影響。並考量電池的實用性,實驗證實適當的進行陰端單邊加濕供氣,有助於陰極端的排水控制,也可改善濃差極化的現象。
Metal foam is used in this study to replace the traditional graphite flow field plate. Using commercial catalyst coated membranes, single fuel cell stack is assembled to investigate the effects of entrance and outlet flow channel design, reactant flow rate, operation temperature, and humidification temperature on cell performance.
Metals have good electrical conductance and mechanical strength, which are suitable for bipolar plates in fuel cell stacks. Previous studies have shown that fuel cells using metal foam to replace traditional flow channels can have very good performance. The purpose of this study is to investigate the operation performance and characteristic of different entrance and outlet fuel channel designs. In addition, the effects of inlet and outlet gas distribution uniformity on the cell performance are also investigated in this study.
The results show that the performance of the fuel cell stack is improved by using new entrance and outlet design that helps the reactants to distribute more evenly. The effect of inlet and outlet design is significant than operation temperature, and humidification temperature. In order to get better cell performance, suitable humidification in the cathode is required. For long-term operation, periodic purging in the cathode can reduce the polarization loss due to mass transfer.
