Described herein is a method for manufacturing a catalytically-active membrane-electrode-assembly () with one or more, particularly two electrodes, the method comprising at least the steps of: i) depositing a heterogenous layer () on a substrate (), the heterogeneous layer () comprising a base metal () and a noble metal () heterogeneously distributed in the heterogenous layer (), ii) leaching of the base metal () out of the heterogeneous layer (), such that a first self-supporting nanoporous catalyst layer () comprising the noble metal () is formed on the substrate (), iii) adding of at least one kind of proton-conductive ionomers () and/or at least one kind of hydrophobic particles () and/or an ionic liquid () to the first self-supporting nanoporous catalyst layer (), and iv) forming a catalytically-active membrane-electrode-assembly () by attaching the self-supporting nanoporous catalyst layer () to a first side of a membrane (), such that a catalytically-active membrane-electrode-assembly () with one electrode is formed.
