Abstract

An electrode based on conductive material and macromolecular materials as the binder, which is stable under electrolysis conditions and is particularly suitable for drying masonry, comprising PA1 (A) a thermoplastic polar polymer, polycondensate or polyadduct or a mixture thereof, which is wettable by an electrolysis medium and is stable with respect to an electrochemical process taking place on the electrode, and PA1 (B) a mixture in a weight ratio of 1:4 to 4:1 of PA2 (a) conductive carbon black with a BET-surface of more than 600 m.sup.2 /g and/or an intrinsically conductive polymer and PA2 (b) carbon black with a BET-surface of less than 600 m.sup.2 /g and/or graphite and/or transition metal oxides and/or an intrinsically conductive polymer.
