  7. 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。
