end gas meaning in English
尾气
最终气体
Examples
- 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
在传统流道设计的pemfc中，反应物从流道到催化层的供应和生成物从催化层到流道的排出主要是以扩散为主，而在交叉梳状流道设计中，以流动带动的对流传递则占据了主导地位，而且这种以对流为主的传递机理大大提高了反应物和产物传递速率，从而有效地改善了电池的极限电流密度和极化性能等特性。
