## Abstract In this work, an experimental study of gas dilution on the performance of a polymer electrolyte membrane (PEM) fuel cell was carried out. Impedance spectra were analysed depending on the dilution of either hydrogen or oxygen by nitrogen. By comparison of the impedance spectra obtained,
The compression induced by the assembly of proton-exchange membrane (PEM) fuel cells causes partial deformation of the gas-diffusion layers (GDLs) and affects the characteristics of the porous media and, consequently, influences the performance of PEM fuel cells. The objective of the present study i
