Described is a method of manufacturing a catalyst membrane, the method comprising the steps of providing a membrane; generating an aerosol of catalyst nanoparticles by spark ablation; and directing the aerosol of catalyst nanoparticles towards a first side of the membrane such that the catalyst nanoparticles are deposited onto the membrane thereby forming the catalyst membrane. Also described is a catalyst membrane comprising a membrane and catalyst nanoparticles attached directly to the membrane in a binder-free manner. L'invention concerne un procédé de fabrication d'une membrane catalytique, le procédé comprenant les étapes consistant à fournir une membrane ; générer un aérosol de nanoparticules catalytiques par ablation par étincelle ; et diriger l'aérosol de nanoparticules catalytiques vers un premier côté de la membrane de telle sorte que les nanoparticules catalytique sont déposées sur la membrane, formant ainsi la membrane catalytique. L'invention concerne également une membrane catalytique comprenant une membrane et des nanoparticules catalytiques fixées directement à la membrane sans liant.
