Aim of the present work is to analyse the effect of the preparation procedure when GDEs are obtained via spray coating of the catalytic layer. A commercial carbon cloth GDL coated with MPL was used as substrate of the catalytic ink that was sprayed onto it, using two different aerograph nozzle dimensions. The prepared GDEs were assembled into a fuel cell lab prototype using commercial polymeric membrane (Nafion Membrane N212) and bipolar plates (Fuel Cell Technologies). Their performances were tested in terms of steady-state polarization and power densities curves and compared with those of a commercial reference GDE.
