在这项工作中，强调了电位和电流分布分析的重要性，作为节能电凝（EC）反应器设计中的关键因素。尽管存在三种类型的电流和电势分布（一次、二次和三次），但作为第一种方法仅分析一次电势和电流密度分布。该方法仅考虑细胞几何形状，从而简化了分析。这项研究包括电位和电流分布的建模及其对 EC 性能的影响。分析显示了电池几何形状和电极配置对电池中电势分布、阳极上的电流分布以及通过改变电极配置来修改不均匀分布的影响。对不同电极配置的实验评估表明，当实现均匀的电位和电流密度时，EC 性能得到增强，并且可以在不改变所施加的电流密度的情况下改善阳极（在本例中为铝）溶解的动力学。
In this work, the importance of potential and current distribution analysis is highlighted as a key factor in the design of energy efficient electrocoagulation (EC) reactors. Although there are three types of distribution of current and potential (primary, secondary and tertiary), only primary potential and current density distributions were analyzed as a first approach. This approach simplifies the analysis by considering only cell geometry. This study included modeling of potential and current distribution and its impact on EC performance. The analysis showed the effect of cell geometry and electrode configuration on the distribution of potential in the cell, the current distribution on the anodes and the modification of a non-uniform distribution by changes to electrode configuration. The experimental evaluation of different electrode configurations showed that EC performance is enhanced when uniform potential and current density is achieved, and kinetics of anode (in this case aluminum) dissolution can be improved without having to change the applied current density.
