ABSTRACT:
An electrode for use in electro-chemical corrosion protection systems, such as cathodic and anodic metal corrosion protection, is in electric contact with a ionically conducting medium. It comprises at least two electrically non-conducting barriers, spaced apart along the electrode. Between the barriers an active part of the surface of the electrode is formed, which active part is in electric contact with the conducting medium. The barriers have a substantial extension outwards from said active part of the surface of the electrode into the conducting medium, so as to homogeneize the current distribution along said active part of the surface of the electrode. (FIG. 7A)
