Abstract : The patent describes an impressed current cathodic protection device which includes a structure having high anodic electrolytic resistance and low electronic pressure resistance. One face of the structure is coated with platinum which is the effective anode and the structure disposed in a dielectric housing except for the one face and a portion of the opposite face. The anode and the housing are positioned in an aperture in the hull of a ship below the waterline with the coated surface facing outwardly and flush with the hull surface. The housing abuts the aperture walls while a stem portion is threaded through the housing or welded so as to form a pressure contact with the anode structure. A non-electrically conducting stuffing gland provides a watertight seal between the stem and the aperture walls. Current passing between the stem-anode and the ship's hull provides cathodic protection for the metal hull.
