Abstract

Electrochemical Impedance Spectroscopy can be used as a diagnostic tool for fuel cells. In this thesis, a model based impedance analysis of Polymer Electrolyte Membrane Fuel cells is given. The impedance of Cathode Gas Diffusion Layer (GDL) and Cathod Catalyst Layer (CCL) is obtained using physical models from existing literature. The change in the oxygen concentraion at the GDL j CCL interface with respect to a perturbation in the current density is obtained from existing models and shown numerically. Similarly, the change in the activation overpotential at the CCL j membrane interface with respect to a perturbation in the current is again calculated from existing models and calculated numerically.
