  "textContent": "The invention relates to the field of electrochemical cells and fuel cells, more specifically to membrane fuel cells such as polymer-electrolyte-membrane fuel cells (PEMFC) and DMFC and describes a continuous process for the manufacture of gas diffusion layers (GDLs). The process comprises a continuous compression step by hot rolls to flatten the GDL prior to the assembly to membrane-electrode-assemblies (MEAs). Due to the low total surface roughness of the GDLs, less damage and perforation of the ionomer membrane occurs and the MEAs made therefrom reveal improved performance.",
