本研究的目的利用實驗以及數值模擬的方式，探討以新型波型流道取代一般平面式的流道設計對於質子交換膜燃料電質的影響。
在實驗的過程中，開路電壓值量測出來的大小為0.85伏特。實驗結果可以發現在波型流道中陽極端與陰極端流量比為1：3可以得到較佳的性能。兩者流量比超過1：3時，空氣的流量的增加反而讓燃料電池的性能降低。一般燃料電池的操作電壓為0.6伏特，而在波型流道設計最佳的操作電壓約為0.4伏特。
另一方面，利用數值模擬的方式研究波型流道內的速度場、濃度場以及燃料電池性能。研究的結果顯示波型流道的設計有益於提升內部的質量傳輸，並改善值子交換膜燃料電池的性能。這是由於受到流道幾何形狀改變產生較強的強制對流影響，使得更多的反應氣體能夠流入擴散層。與傳統的平行式流道比較，當波型流道的波峰與擴散層間的間隙變小時，會有更顯著的影響。在波型流道與擴散層間的間隙變小的同時，也讓燃料電池內的壓降增加。當其間隙大小大於0.3可以獲得較為理想的壓降影響。整體來看，波型流道的設計可以讓燃料電池比一般的直線型流道的性能提升約30%的功率密度。
在受限制的流場空間中，討論不同的流道設計對於燃料電池性能、壓降以及熱傳的影響。在方形凸塊設計中，兩個以及四個方形凸塊的設計比平行式流道多消耗了8.75%的氧氣。在燃料電池的性能表現，也較其他的設計來的好。同時，可以發現到流道到凸塊的排列方式也會對於燃料電池的性能產生明顯的影響。在熱傳方面，侷限的空間下的條件下，流道內的方形凸塊可以有效改善總體的熱傳效果，其增益約為20-30%，但方形凸塊數量有一定的上限。

The objective of this study is to use a new style of waved flow channel instead of the plane surface channel in the proton exchange membrane fuel cell (PEMFC) by the experiment and numerical simulation.
In the experiments, the open circuit voltage (OCV) is measured about 0.85V. The results show that the better flow ratio for anode to cathode is closed to 1:3 in the wavelet channel. In the high cathode flow rate, the performance decays when the ratio is over 1:3. At a general condition, the operation voltage is about 0.6 V, but the better operator voltage of wavelet flow channel is about 0.4V.
The velocity, concentration, and electrical performance with the waved flow channel in PEMFC are investigated by numerical simulations. The results show that the waved channel arises when the transport benefits through the porous layer, and improves the performance of the PEMFC. This is because the waved flow channel enhances the forced convection, and causes the more reactant gas flow into the gas diffusion layer (GDL). The performance which was compared to a conventional straight gas flow channel increases significantly with the small gap size when it is smaller than 0.5 in the waved flow channel. The pressure drop is increased as the gap size becomes smaller, and the wave number decreases.δ(gap size)>0.3 has a reasonable pressure drop. Consequently, compared to a conventional PEMFC, the waved flow channel improves approximately 30% power density.
In the restricted flow field, the performance, the pressure drop and the heat transfer are discussed for the different design. For the block design, the oxygen consumed fraction is about 8.75% greater for the 2 and 4-block channel in comparison with the straight channel for the voltage of 0.5V. For the performance, it is shown that 2-block and 4-block design are better than the others. It is signature that the arrangement of the block in the flow channel affects the performance of the fuel cell. For heat transfer, the blocks in the flow channel can improve about 20-30%, but the number of the blocks in the flow channel exist the upper limit.
