One-Dimensional Impedance of the Cathode Side of a PEM Fuel Cell: Exact Analytical Solution
2014
Journal of the Electrochemical Society
A transient one-dimensional model for the coupled performance of the cathode catalyst layer (CCL) and the gas-diffusion layer (GDL) in a PEM fuel cell is linearized and an exact analytical solution for the cathode side impedance Z is derived. The solution is valid at a low current density, when the proton and oxygen transport losses in the CCL are not large. The zero-frequency resistance contains the faradaic term, the terms due to the proton and oxygen transport in the CCL and due to the
