摘要
建立了固体聚合物电解质(SPE)水电解池电迁移和反扩散水传递的关联模型;利用Matlab软件,求解了沿水流方向的膜两侧水含量及净水传递系数α分布;得到了沿水流方向的膜水含量分布函数,探索了水量不足时的水传递机理。对SPE水电解池的阻抗分布模型进行验证,证明了模型的符合性。
In this paper, a water transport model of solid polymer electrolyte water electrolyzer(SPE WE) was established,which was about water electro-osmotic drag and back diffusion transport. By means of Matlab, the water content in both sides of membrane and the net water transport coefficient(α) distribution along the channels were resolved. Finally, the water content distribution function of membrane along the channels was obtained, and the mechanism of water transporting through the membrane was explored. The impedance data of SPE WE validated the model.
