Numerical Simulation of Electrochemical Processes and Devices

This article summarizes the author's recent research on numerical simulation of electrochemical processes and devices. Two approaches are presented : finite element method (FEM) simulations and ordinary differential equation (ODE) models. FEM enables detailed analysis of battery lifetime and pH distribution in electrolysis, whereas ODE models, based on Randles-type circuits and Nernst diffusion layers, capture essential dynamics such as pH variations and corrosion oscillations. Together, these methods offer device-level analysis and mechanistic insight for next-generation electrochemical technologies.
