Method for producing an electrolytic catalyst support, electrolytic catalyst support and electrochemical electrode

A method for the production of an electrolytic catalyst support for electrochemical applications by depositing particles of electrolyte material (I) on a substrate of (I), involves heating the substrate and/or the particles. Independent claims are also included for (1) electrolytic catalyst supports in which the electrolyte surface/interface (32) is formed by particles of electrolyte material bound to a substrate (10) of electrolyte material (2) electrochemical electrodes containing a catalyst support as above .
