Catalytic polymer electrode for cathodic protection and cathodic protection system comprising same

Abstract From the Canadian patent

A catalytic polymer electrode comprises a current conducting polymer body forming an electrode base which is provided with catalytic valve metal particles fixed to its surface. A current conducting body of carbon filled thermoplastic polymer preferably containing conductive fibres is heated to soften its outer surface and the, catalytic valve metal particles are pressed onto its softened surface and thereby attached to the surface of the polymer body. Such a catalytic polymer electrode used as an anode in an impressed-current cathodic protection system comprises a catalyst to provide a reduced oxygen potential. Such catalytic polymer anodes may be applied in systems for impressed current …
