Abstract

Known prior art catalyst pastes are, as a rule, to liquid for coating by means of silk-screen printing or colour ductors. The invention relates to a method for the production of a catalyst paste, containing an acidic ion exchanger and specific base polymers, which is especially suitable for coating methods such as silk-screen printing and colour ductors due to the viscosity thereof. A catalyst layer produced with said inventive catalyst paste does not regularly display any loss in performance compared to catalyst layers produced by prior art standard catalyst pastes. Even improved performance properties are partially obtained.
