本文之目的在探討質子交換膜(PEMFC,Proton Exchange Membrane Fuel Cell )燃料電池燃料分隔板流道中加入微小凸塊的燃料傳輸現象,相關研究的問題包括壓力降、速度場、摩擦阻力及電流密度等物理模型。
研究方法乃先以計算流體力學之套裝軟體PHOENICS來模擬流道內凸塊的狀況,藉以了解流道內流場的趨勢、壓力的分佈及出口的狀態,再配合剪應力、摩擦阻力之模形計算出燃料電池陽極端的輸入燃料的傳輸現象,提供陽極燃料流道設計者流道內凸塊的最佳狀況。
結果顯示凸塊、摩擦阻力與壓力降等呈現出一種比值關係,而輸出電流密度正比紐塞數,而紐塞數又正比於摩擦阻力,而根據Mickley所述便可證明上述關係。因此可由此種特別的比率關係來決定最佳輸出電流下流道中最佳凸塊高度,進一步可以改善陽極燃料傳輸至電極板的狀況,另一方面亦可藉此提昇燃料電池的電流密度。


The purpose of this study is to investigate the transport phenomena for a channel with ribs in the PEMFC fuel cell. The topics include the pressure drop, velocity field, friction coefficient and current power density.
The model was simulated the channel with rib condition using the software PHOENICS and obtained the flow field, pressure drop and the outlet states. Then we calculate the shear stress, the friction coefficient and the transport phenomena in the anode of the fuel cell. It showed the better conditions of the rib structure inside the channel for the design of the anode fuel channel.
The results showed that pressure drop, friction coefficient, output current power density, and Nusselt number were increased with an increasing rib height. The results have a good agreement with Mickely’s state. Thus the better height of the ribs inside the channel by output current could be decided using this relation. In addition, the design of plate structure of channel in the anode fuel can be improved, and the current power density of the fuel cell can be enhanced.
