摘要

在质子交换膜燃料电池（PEMFC）性能较差的平行直流场中,增加错列布置的三维变径结构,采用三维非等温CFD模型进行数值模拟,研究该流道设计中的传质机理。结果表明,三维变径流道可增加流道与气体扩散层垂直方向上的氧气浓度梯度,并在流道内、2条流道之间形成高速对流传质,可有效提升气体扩散层内的氧气浓度及PEMFC性能。变径高度降低时,PEMFC性能先提升后明显降低,在变径高度0.3 mm时,性能最佳。与直流场相比,此时在0.54 V下的电池输出电流密度、系统净功率分别提升18.14%和17.61%。

Abstract

In this work, staggered three-dimensional （3D） partially narrowed structures are added to improve the poor performance of conventional parallel straight flow field in proton exchange membrane fuel cells （PEMFCs）. Numerical simulations using a 3D non-isothermal CFD model are employed to investigate the mass transfer mechanisms of this novel flow channel configuration. Results show that, compared with the parallel straight flow channels, the 3D partially narrowed flow channels increase the vertical oxygen concentration gradient between the channel and the gas diffusion layer （GDL）, and generate high-speed convective mass transfer within channels and between adjacent channels, thereby effectively enhancing the oxygen concentration in the GDL and PEMFC performance. When the narrowed section height decreases, PEMFC performance initially improves and then significantly decreases. The optimal performance is achieved when the narrowed section height is 0.3 mm. Compared with the parallel flow channels, at this configuration, the output current density and system net power of PEMFC at 0.54 V increase by 18.14% and 17.61%, respectively.
