摘　　要：介绍了水向双极性膜中迁移的速度与膜的最大电流密度之间的关系 .理论分析和初步实验说明水的迁移可以用溶解扩散机理来描述 ,为提高膜的最大电流密度必须提高膜对水的迁移能力 .Correlation of water transport rate with maximum current density of a bipolar membrane was studied. Water transport process can be described by solution-diffusion model. Material with high water permeability could be used to prepare bipolar membrane in order to increase its maximum current density.
