5 The method is a preparation of an ink which can be used for the manufacture of a functional layer, in particular for the manufacture of an electrode for fuel cells.The ink contains dispersely distributed particles forming two solid phases. Catalytic reactions can be activated in the manufactured functional layer on a gas/solid interface by a combined action of 10 the two solid phases and with gaseous reactants.In a first step,the solid phases are formed as fine-grain particles.The particles of both solid phases are mixed and dispersed in a bomogeneously distributed manner in a first liquid. Heterogeneous conglomerates of the fine-grain particles are formed from the dispersion arising in this connection.These conglom 15 erates are mixed to form a hgomogeneous ink after sintering by adding a second liquid and while being crushed.The particles formed in the first step have such a fine grain that the heterogeneous conglomerates and their fractions each contain a plurality of particles of both solid phases after the crushing. 20
