采用COMSOL多物理软件进行有限元数值计算，计算了扫描式流动电池(SFC)的电解液流动分布和活性物质浓度分布。在动力学参数接近氧还原反应动力学参数的简单一步反应情况下，证明了传统的库特西利-莱维希(KL)分析方法在动力学电流计算中的适用性。此外，还研究了单元几何形状，特别是进出口管角和管径的影响，以指导该方法的进一步优化。以氧还原反应为例，验证了动力学分析的适用性。(C)提交人(S)2015年。由ECS出版。这是一篇开放获取文章，根据知识共享署名4.0许可证(CC by，http://creativecommons.org/licenses/by/4.0/)，)的条款分发，该许可证允许在任何介质中不受限制地重复使用作品，前提是正确引用原始作品。版权所有。
The electrolyte flow profile and reactive species concentration distribution are calculated for a Scanning Flow Cell (SFC) by means of finite element method numerical calculation using COMSOL Multiphysics software. In case of a simple one-step reaction with kinetic parameters close to those of the oxygen reduction reaction the applicability of conventional Koutecicy-Levich (KL) analysis for the kinetic current calculations is proved. In addition, the influence of the cell geometry, particularly the angle between inlet and outlet tubes and the tube diameter, is investigated to guide the further optimization of the method. The applicability of the kinetic analysis is demonstrated experimentally on the example of oxygen reduction reaction. (C) The Author(s) 2015. Published by ECS.
