Abstract

In a method for producing a proton-conductive, structured electrolyte membrane, particularly for a fuel cell, a coating, which comprises at least one ion-conductive cross-linking component having at least one acid group and at least one photoactive substances interacting therewith, is applied onto a solid body surface. The coating is optically masked in that at least one region of the coating, in which the electrolyte membrane is supposed to be, is exposed such that the cross-linking component cross-links with the photoactive substances to form a polymer and/or copolymer network adhering to the solid body surface. At least one unexposed region of the coating is removed in order to structure the electrolyte membrane.
