    Abstract: 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。
    ;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.
