Zusammenfassung:	A process for producing a membrane-electrode assembly for a fuel cell. The process (a) produces at least one multilayer field on a support, with the at least one multilayer field including at least one electrode layer and at least one membrane layer and the at least one multilayer field being applied to the support such that the at least one multilayer field is surrounded by channels on the support that are bounded on at least one side by edges of the at least one multilayer field, and (b) introduces a flowable, curable sealing material into the channels, which sealing material becomes distributed there to produce a seal surrounding the edges of the at least one multilayer field.
