The transmission line model (TLM) is a powerful tool to describe different physicochemical processes and therefore frequently used for the simulation of battery fuel cell performance. Despite fact that TLMs exhibit spatial resolution, there still are challenges when applying realistic geometries modelling arbitrary direct alternate current operations. To resolve this long-standing challenge, we developed methodology designing TLMs, which enables adequate operations on simplified active intercalating particles in electrodes. insightful derivation based finite volume discretization diffusion equation particles. capability proposed method adequately AC DC operation demonstrated by comparing obtained results with analytic solution. This was validated spherical geometry solid diffusivity coefficients
