The present invention relates to a method for producing a membrane for a fuel cell or electrolytic cell, in which (i) a liquid coating composition, which contains a supported catalyst containing precious metal and also contains an ionomer, is applied to a polymer electrolyte membrane which contains an ionomer, the ionomer of the liquid coating composition and the ionomer of the polymer electrolyte membrane each being a copolymer which contains as monomer a fluoroethylene and a fluorovinyl ether containing a sulfonic acid group, (ii) the coated polymer electrolyte membrane is heated to a temperature in the range from 178° C. to 250° C.

Method for producing a catalyst-coated membrane

An electrical conductor has a first layer, wherein the first layer is electrically conducting, and has micro protrusions, macro protrusions, wherein the micro protrusions are arranged on the macro protrusions, a first set of depressions, wherein the first set of depressions comprises at least two longitudinal depressions; the macro protrusions and the at least two longitudinal depressions are arranged in an alternating pattern, at least one coating layer, wherein the at least one coating layer comprises an electrically conducting polymer, touches the first layer, at least partially covers the first layer; wherein at least 50% of the macro protrusions have a width, measured along a first direction in the range of 2.0 mm to 40.0 mm and at least 50% of the micro protrusions have a width, measured along the first direction, in the range of 0.001 mm to 1.000 mm.
