Here is the rephrased text:

Electrochemical Phenomena in the Cathode Impedance Spectrum of PEM Fuel Cells: Fundamentals, Modelling, and Applications delves into the intricate relationship between the electrochemical and diffusion mechanisms of a polymer electrolyte membrane fuel cell (PEMFC) and electrochemical impedance spectroscopy (EIS) measurements. By employing physics-based impedance models derived from fundamental electrode and diffusion theories, this comprehensive text unravels the contribution of various phenomena occurring at different layers within the cathode of the PEMFC. Through EIS-modelling analysis, it sheds light on how these phenomena shape the impedance response of the PEMFC. Furthermore, it establishes a connection between EIS measurements and polarisation curves, representing the performance of PEMFCs. By employing physics-based impedance models, the text provides valuable insights into how the EIS response of the PEMFC varies under different operating conditions, such as relative humidity, load demand, gas reactant stoichiometry, and temperature. Additionally, it showcases the application of impedance models alongside EIS measurements conducted in individual cells within a PEMFC stack. Furthermore, the text explores recent modelling approaches and other impedance models reported in the literature to represent the EIS response of the PEMFC. This comprehensive exploration of electrochemical phenomena in PEM fuel cells underscores the importance of understanding these mechanisms in advancing the development and optimisation of this renewable energy technology.
