An electrode for an electrochemical cell used in strip coating systems for continuous metal sheets has a plate-shaped electrode carrier, to which activated electrode components are connected mechanically in a detachable manner. The electrode carrier contains a metal core of material with good electrical conductivity, which, with the exception of the points where the activated electrode parts are connected, is surrounded by a jacketing of valve metal; on the side of the electrode carrier facing the cell wall, a corrosion- resistant plastic body in attached, against which the support means, the spring elements, the positioning elements, or the flow guide elements extending from the cell wall rest, these supports or elements thus being unable to cause any damage to the valve-metal jacketing of the electrode carrier.

Electrode

An electrode structure for membrane electrolysis cells comprises a planar electrode part which is joined by metal spacers to a sheet metal support serving as current distributor. The spacers are made in the form of a spring clip mounting comprising a spring part and a springless part, the spring part being fixedly joined to the support while the springless part is integral with the electrode part. In case of the need to reactivate or repair the active electrode parts the spring clip mounting permits them to be separated easily from their supports and then they can be sent away directly for reactivation or repair.

Electrode structure

A novel method of renewing electrode surfaces of metal electrodes with elongated supporting riser with at least the surface thereof being comprised of a valve metal or valve metal alloy supporting a generally planar electrode member with an electrocatalytic coating thereon.
