Abstract
A method for continuous coating of a solid electrolyte (3) with a coating comprised of a catalytically active metal, comprising impregnating the solid electrolyte (3) (present in the form of a film comprised of a plastic polymer) with a solution of a metal salt, and electrolyzing the metal salt in a plurality of passes of the solid electrolyte (3) between two rolls (4, 5) which rolls serve as electrodes, in a water bath, wherewith at first the speed of advance of the solid electrolyte film is a relatively high value of 20 to 30 cm/min and then a lower value of 1 to 2 cm/min, and wherewith the linear current density in the line of contact between the rolls (4, 5) and the solid electrolyte (3) is at least 830 mA/cm.
