Beschreibung
Zusammenfassung:	The method comprises applying a coating, which comprises an ion-conductive cross-linking component having an acid group and a photoactive substance interacting with the cross-linking component, onto a solid body surface, optically masking the coating in that the region of the coating, in which the electrolyte membrane is to be supposed, 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, and removing an unexposed region of the coating to structure the electrolyte membrane. The method comprises applying a coating, which comprises an ion-conductive cross-linking component having an acid group and a photoactive substance interacting with the cross-linking component, onto a solid body surface, optically masking the coating in that the region of the coating, in which the electrolyte membrane is to be supposed, 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, and removing an unexposed region of the coating to structure the electrolyte membrane. The cross-linking component and the photoactive substance that are dissolved in a solvent are applied onto the solid body surface by spin coating and then the solvent is evaporated for forming the coating. The acid group is sulfonic acid group, phosphoric acid group or carboxylic acid group. An independent claim is included for a method for producing a fuel cell.
