Abstract
An antifouling system ( ) for a structure exposed to seawater has an anode forming member ( ) bonded to the seawater-exposed surface to be wetted with seawater ( ) of the structure via an insulating adhesive ( ). The anode forming member is coated with an electrical catalyst film of an electrochemically active and stable electrical catalyst. A conductive member ( ) is disposed so as to be wetted with seawater ( ). An external dc power supply ( ) has a positive terminal ( ) connected to the anode forming member ( ) and a negative terminal ( ) connected to the conductive member ( ). The external DC power supply ( ) is provided with a built-in automatic potential controller ( ) that controls the potential difference between the positive terminal ( ) and the negative terminal ( ) such that oxygen can be generated in seawater suppressing the generation of chlorine in seawater. Even if a rubber lining coating a metal part of the structure is broken, abnormal corrosion of the metal part corresponding to a damaged part of the rubber lining can be prevented.
