1. Proton exchange membrane-based electrolyser comprising an anode portion, a cathode portion and a proton exchange membrane;
the anode portion arranged at a first surface side of the membrane and the cathode portion arranged at a second opposite surface side of the membrane;
the anode portion comprising an anodic catalyst layer and an anodic porous transport layer; the anodic catalyst layer being arranged between the anodic porous transport layer and the first surface side,
the cathode portion comprising a cathodic catalyst layer and a cathodic porous transport layer; the cathodic catalyst layer being arranged between the cathodic porous transport layer and the second surface side,
wherein the electrolyser comprises a conductive first mesh foil and/or a conductive second mesh foil,
the conductive first mesh foil being stacked on the anodic catalyst layer such that a surface of the mesh foil covers the surface of the anodic catalyst layer in a first covered area and providing a first conducting interface between the mesh foil and the anodic catalyst layer in the first covered area,
the conductive second mesh foil being stacked on the cathodic catalyst layer such that a surface of the mesh foil covers the surface of the cathodic catalyst layer in a second covered area and providing a second conducting interface between the mesh foil and the cathodic catalyst layer in the second covered area,
wherein either the respective mesh foil is arranged between the anodic catalyst layer and the proton exchange membrane or between the cathodic catalyst layer and the proton exchange membrane,
or the respective mesh foil is arranged between the anodic catalyst layer and the porous transport layer or between the cathodic catalyst layer and the porous transport layer.
