Proton Exchange Membrane Fuel Cell (PEMFC) is majorly used for power generation without producing any emission. In PEMFC, the water generated in the cathode heavily affects the performance of fuel cell which needs better water management. The flow channel designs, dimensions, shape and size of the rib/channel, effective area of the flow channel and material properties are considered for better water management and performance enhancement of the PEMFC in addition to the inlet reactant's mass flow rate, flow directions, relative humidity, pressure and temperature. With the purpose of increasing the output energy of the fuel cell, many flow field designs are being developed continuously. In this paper, the performance of various conventional, modified, hybrid and new flow field designs of the PEMFC is studied in detail. Further the effects of channel tapering, channel bending, landing to channels width ratios, channel cross-sections and insertion of baffles/blockages/pin-fins/inserts are reviewed. The power density of the flow field designs, the physical parameters like active area, dimensions of channel/rib, number of channels; and the operating parameters like temperature and pressure are also tabulated.
质子交换膜燃料电池（PEMFC）主要用于发电，且不产生任何排放物。在质子交换膜燃料电池中，阴极产生的水会严重影响燃料电池的性能，因此需要更好的水管理。除了入口反应物的质量流量、流动方向、相对湿度、压力和温度外，还需考虑流道设计、尺寸、肋/流道的形状和大小、流道的有效面积以及材料特性，以实现更好的水管理并提高质子交换膜燃料电池的性能。为了提高燃料电池的输出能量，人们不断开发多种流场设计。本文详细研究了质子交换膜燃料电池各种传统、改进、混合和新型流场设计的性能。此外，还综述了流道渐缩、流道弯曲、着陆与流道宽度比、流道横截面以及插入挡板/障碍物/针翅/插件的影响。文中还列出了流场设计的功率密度、诸如有效面积、流道/肋的尺寸、流道数量等物理参数，以及诸如温度和压力等运行参数。
