  5. The flow characteristics, distributions of current density and chemical components, and the performance of these two different designs are calculated and compared. the flow and mass transport characteristics are analyzed in detail, which indicate that strong forced convection is produced in the interdigitated flow field, which consist of dead - end gas channel that force the gases through the porous electrodes. results of comparison show that forced convection induced by the interdigitated flow field in the diffusion layer effectively enhances mass transport of reactants and products, thus leading to a higher cell performance and the limiting current density

    在傳統流道設計的pemfc中，反應物從流道到催化層的供應和生成物從催化層到流道的排出主要是以擴散為主，而在交叉梳狀流道設計中，以流動帶動的對流傳遞則占據了主導地位，而且這種以對流為主的傳遞機理大大提高了反應物和產物傳遞速率，從而有效地改善了電池的極限電流密度和極化性能等特性。

Skin effect is the tendency for alternating current to flow near the sruface of the conductor in lieu of flowing in a manner as to utilize the entire cross - sectional area of the conductor. this phenomenon causes the resistance of the conductor to increase. the magnetic field associated with the current in the conductor causes eddy currents near the center of the conductor which opposes the flow of the main current near the center of the conductor. the main current flow is forced further to the surface as the frequency of the alternating current increase

    表面疚是指交流電流較傾向于導體的表面傳導而非流經整個導體截面的趨勢，這些現象會造成導體的電阻提高，與導體中的電流有關的磁場在導體中心部位產生過電流而阻礙了中心部位的主要電流，當交流電的頻率增加時，主要電流的流向會進一步被推擠到導體表面。
