## Abstract This paper discusses the effect of compression pressure on the mechanical and thermal properties of gas diffusion layers (GDL). The stress–strain curve of the GDL revealed one nonlinear and two piecewise linear regions within the compression pressure range of 0–5.5 MPa. The thermal cond

## 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,
