可以看出,对于电流而言,离子的质量传递(mass transfer)才是其本质。在本体溶液中,主要是迁移电流。在电极表面同时存在扩散电流和迁移电流。电解质承担了迁移电流的大部分,消除了迁移对于电化学活性物质传质的影响,简化了其传质方程的数学处理,也同时降低了溶液电阻。 今天的内容到此为止,欢迎一起探讨。

An accurate mathematical description of the charge transfer rate at electrodes due to an electrochemical reaction is an indispensable component of any electrochemical model. In the current work we use the generalized Frumkin-Butler-Volmer (gFBV) equation to describe electrochemical reactions, an equation...
Mass transport in reverse electrodialysis for sustainable energy generation At the electrodes a redox couple is used to mitigate the transfer of electrons. The ion exchange membranes are one of the key elements in the RED process as they, together with ion transport phenomena and concentration polari...
