An extremely high temperature of anode humidification is also unreasonable; as a result, when the current density is high, the liquid water should be injected directly into anode gas channel to guarantee both high inlet H〓 concentration and well-humidified membrane. 4. The utilization of Pt in the cathode catalyst layer will decrease with the increasing current density; as a result, based on the principle of maximal Pt utilization, the catalyst layer can be designed much thinner or not uniformly in the catalyst distribution.

而在此截面上，交指型流场燃料电池阳极侧的液态水饱和度的极值位置并不确定；在电池阴极处，液态水饱和度的极值总是出现在z=0.002m处的气体扩散层和膜的界面上，并且该处的液态水饱和度沿x方向存在一个最大值，与此相应的氧气的质量浓度分数在该处达到极小值，因此极限电流密度将首相出现该处，但总体来说液态水饱和度沿x方向的分布较为均匀。4。

The results show that when the cathode humidified temperature increase, the humidification of membrane and fuel cell performance improved at lower current density, while the saturation in diffusion layer increase and the performance decreases at higher current density. Humidification of membrane and fuel cell performance improved when the anode humidified temperature increase, the saturation in diffusion layer decrease and fuel cell performance improved when the fuel cell working temperature increase, the resistance of diffusion layer decrease and the performance improved when the porosity largen. At last, the simulation results are compared with the experimental results and they are basically the same.
