The presence of water in the flow field greatly affects the performance of PEM fuel cell. One of the problems is caused by the water imbalance in the PEM fuel cell. If the water content is too high it causes flooding in the PEM fuel cell stack. As a result, the distribution flow of raw materials (hydrogen and oxygen) flowing into the stack is blocked. Conversely, if it is too dry it will cause the membrane to crack. Both cases resulted in a decrease in the performance of the PEM fuel cell system. The method used for water management in the flow field of a bipolar plate flow Computating Fluids Dynamics (CFD) software. The results showed that the highest water content occurred in the spiral flow field at a flow rate of 4 x 10^-8 kg/s with a water content of 0.75 g/g. The lowest water content occurs in the multiple channel serpentine flow field at a flow rate of 4 x 10^-8 kg/s with the water content of 0.47 g/g. In this condition the performance of PEM fuel cell is relatively stable in the single channel serpentine flow field with a flow rate of 4 x 10-8 kg/s and a depth of 0.3 mm because the formation of water is insignificant compared to using other flow fields.

流场中水的存在极大地影响了PEM燃料电池的性能。问题之一是由 PEM 燃料电池中的水不平衡引起的。如果水含量太高，则会导致 PEM 燃料电池堆发生溢流。结果，流入堆栈的原材料（氢气和氧气）的分配流被阻塞。相反，如果太干，则会导致膜破裂。这两种情况都导致 PEM 燃料电池系统的性能下降。双极板流动计算流体动力学 (CFD) 软件流场中用于水管理的方法。^{结果表明，在流速为4×10 -8}的螺旋流场中含水量最高。kg/s，含水量为 0.75 g/g。含水量最低的是多通道蛇形流场，流速为4×10 ^-8 kg/s，含水量为0.47 g/g。在这种情况下，PEM 燃料电池的性能在单通道蛇形流场中相对稳定，流速为 4 x 10-8 kg/s，深度为 0.3 mm，因为与其他流相比，水的形成微不足道。字段。
