Abstract

A textile can be configured as a spacer between a housing or a supporting structure and an electrode or a substructure of an electrode of a zero-gap electrolytic cell. The textile may comprise a mechanical connection means composed of an elastic polymeric material and may comprise an electrical connection means different from the mechanical connection means. A zero-gap electrolytic cell can be furnished with such a textile. Further, a method for producing such a zero-gap electrolytic cell may be characterized in that at least one ply of a textile is placed into an anode tank or cathode tank, an anode or cathode electrode is disposed on the at least one ply of the textile, an ion exchange membrane is placed onto this electrode, and a cathode electrode or anode electrode connected to a cathode tank or anode tank, respectively, is disposed on the ion exchange membrane.
