Impedance Analysis of Polymer Electrolyte
Membrane Fuel cell.
Masters thesis, Indian Institute of Technology hyderabad.
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.
