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.

不同流场设计的质子交换膜燃料电池性能研究–综述

质子交换膜燃料电池（PEMFC）主要用于发电而不会产生任何排放。在PEMFC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，流向，相对湿度，压力和温度。为了增加燃料电池的输出能量，许多流场设计正在不断发展。在本文中，详细研究了PEMFC的各种常规，改进，混合和新流场设计的性能。此外，还审查了通道逐渐变细，通道弯曲，着陆与通道宽度之比，通道横截面以及插入挡板/堵塞物/销钉/插入物的影响。流场设计的功率密度，有效面积等物理参数，通道/肋的尺寸，通道数；并且还列出了诸如温度和压力之类的操作参数。
