考察了不同电流密度、不同温度下电解液在纳米多孔质子膜中的迁移情况，在多次充放电循环后，钒离子与水均在负极积累，正极电解液体积线性减小，负极电解液体积线性增大，同时研究了电解液迁移对充放电容量的影响，研究表明，钒离子的跨膜迁移会导致充电与放电瓦时容量在不断衰减。
攷察瞭不同電流密度、不同溫度下電解液在納米多孔質子膜中的遷移情況，在多次充放電循環後，釩離子與水均在負極積纍，正極電解液體積線性減小，負極電解液體積線性增大，同時研究瞭電解液遷移對充放電容量的影響，研究錶明，釩離子的跨膜遷移會導緻充電與放電瓦時容量在不斷衰減。

Vanadium electrolyte dynamic transfer across nano- porous proton membrane in the vanadium redox flow battery at different current densities and temperatures was investigated. The results show that vanadium ions and water accumulate in negative side eventually, the positive electrolyte increases linearly and the negative electrolyte decreases linearly. The influence of vanadium electrolyte dynamic transfer on charge/discharge capacity was also studied.The results show that the watt-hour capacity decreases gradually due to vanadium ions transfer across membrane.
