Oxygen transport in the low–Pt catalyst layer of a PEM fuel cell: Impedance spectroscopy study
A model for PEM fuel cell impedance taking into account the pore size distribution (PSD) in the cathode catalyst layer is developed. Experimental PSD is approximated by pores of three sizes (small, medium and large) and in each kind of pores, the oxygen diffusion coefficient is allowed to have a sep...
