Abstract: A bipolar plate for an apparatus having a stacked configuration, said apparatus comprised of a plurality of electrochemical cells and employing a solid electrolyte, said bipolar plate comprised of a porous titanium plate (1) having a parallel groove structure (3), said bipolar plate further comprised of a non-porous, solid titanium plate (2) strongly welded to plate (1) at contact loci (4), wherewith channels (5) are present, and said bipolar plate further comprised of a surface layer or coating (6) comprised of a material which is a catalyst for electrolytic reactions. A method of manufacturing the subject bipolar plate, comprising the following: Powder metallurgical manufacture of the porous titanium plate (1), and bonding of plate (1) to the solid titanium plate (2) by sintering.

Abstract: A process and apparatus for continuously coating a solid electrolyte with a catalytically active metal, whereby large-area sheets of the solid electrolyte are continuously coated in a uniform manner with the catalytically active metals, by first being impregnated with an aqueous solution of the particular metal and subsequently being passed through, in a water bath, between two rolls acting as electrodes, wherein a felt of carbon is arranged on the cathode side interposed between the electrolyte and the cathode roll, and thus being subjected to an electrolysis process.
