摘要

本文介绍了 EC2 方案中用于电化学反应时变分析的新型数学模型。利用同调扰动法，我们解决了高度非线性的反应-扩散方程，即使在非稳态条件下也是如此。我们提供了物种 O 和 R 浓度的近似分析表达式，并对扩散和动力学参数进行了敏感性分析。稳态条件下的结果验证了我们的模型与之前研究结果的一致性。此外，我们还使用 Matlab 和 Maple 软件提供了数值解决方案，证明与实验数据的一致性令人满意。

Chronoamperometric response of electrochemical reaction diffusion system: a new theoretical and numerical investigation for EC2 scheme

This paper introduces a novel mathematical model for chronoamperometric analysis of electrochemical reactions in the EC2 scheme. Utilizing the homotopy perturbation method, we address the highly nonlinear reaction–diffusion equations, even under non-steady state conditions. We offer an approximate analytical expression for species O and R concentrations, along with sensitivity analysis on diffusion and kinetic parameters. Results under steady state conditions validate our model against prior findings. Additionally, we provide a numerical solution using Matlab and Maple software, demonstrating satisfactory agreement with experimental data.
