Analytical transfer function to simulate the dynamic response of the finite-length Warburg impedance in the time-domain

Based on fundamental electrode theory, an analytical transfer function to simulate the frequency impedance spectrum of finite-length Warburg (FLW) and dynamic potential response FLW in time-domain has been developed this study. Parameters reported literature estimated from experimental measurements carried out polymer electrolyte fuel cells (PEFCs) have considered validate new function. The representing can be different equivalent electrical circuit configurations a more accurate output voltage electrochemical power system under effect diffusion phenomena. A Simulink model based Randles is constructed PEFC during current-interrupt incident. In addition, configuration Li-ion battery. This study establishes wider scope relate spectroscopy systems.
