The present invention discloses a method of manufacturing gas diffusion layers (GDL) with a defined pattern of hydrophobic and hydrophilic regions. The method to produce electrically conductive porous materials with distributed wettability comprises the steps of: a) Coating the external and internal surfaces of a porous base material made of carbon fiber or Titanium with Fluoroethylene-Propylene (FEP) and/or perfluoroalkoxy (PFA) and/or Ethylene-Tetrafluoroethylene (ETFE) or any other hydrophobic polymer; b) Exposing the coated material to irradiation through a blocking mask such that only parts of the coated porous material are exposed; c) Immersing the previously exposed material in a monomer solution and heating to a temperature higher than 45°C, resulting in the graft co-polymerization of monomers on the FEP layer
