Abstract
An electrically conductive layer on a solid-body electrolyte (1) is produced by swelling and impregnating an organic ion exchange material (2) with a metal salt solution, drying, converting the metal ions in a gas stream to finely distributed particles (3) which are in electrical contact with one another, renewed swelling in a solvent, converting into a brushable paste and applying same to the surface of the solid-body electrolyte and drying. Preferred embodiment: solid-body electrolyte (1) and ion exchange material (2) made of polymers containing sulphonic acids; and conductive particles (3) made of platinum metals or oxides thereof, in particular ruthenium as electrocatalyst.
