ELECTRODE WITH REVERSIBLE POLARITY

摘要

Electrode of reversible polarity for electrochemical applications, especially those where the electrolyte contains also calcium and magnesium. A multilayer structure is formed that comprises a carrier (1) of a valve metal, a conductive ceramic layer (2) applied onto the carrier and an electrocatalytically active top layer (3). This structure results, on the one hand, in protecting of the carrier (1) and, on the other hand, in the stability of the catalytic layer (3) also in cathodic operation. A continuous charge reversal does not damage the electrode. The equal surfaces of anodes and cathodes may be positioned parallel or substantially parallel facing each other.
