  1. When the air is fed to cathode of pemfc, the oxygen concentration decreases along the channel because of reaction, and the oxygen distribution is affected by land of the flow plate. so the oxygen distribution is uneven on cathode side and leads to dropping of cell performance

    當pemfc陰極供給空氣時,因氧氣在催化層參與反應被消耗,其濃度沿流道逐漸降低,加之受流道間隔的影響,陰極側氧氣濃度不均勻,這導致電池性能惡化。
  2. When the punched baffle is proper in length, the small holes are in staggered arrangement and the punched ratio gradually increases from the central axis to the boundary along the baffle length, the performance of flow distribution in the plate - fin heat exchanger is effectively improved by the optimum design of header configuration

    從實驗對比分析中得出,當擋板小孔呈錯排分佈、開孔率沿擋板的中軸線向兩側逐漸增加、且總開孔率達到50 %左右的時候,在相同的入口條件下,不均勻系數由原始封頭的1 . 210降至0 . 209 ,最大流速與最小流速之比由23 . 163降至1 . 756 。
