Abstract:
An antifouling system that generates oxygen on a seawater-exposed surface of a structure to be exposed to seawater to prevent attachment of marine organisms to the seawater-exposed surface of the structure, said antifouling system comprising:an anode forming member bonded to the seawater-exposed surface of the structure to be exposed to seawater via an insulating adhesive; an electrochemically active and stable electrical catalyst coated on the anode forming member; a conductive member disposed so as to be wetted with seawater; and an external DC power supply having a positive terminal connected to the anode forming member or the electrical catalyst and a negative terminal connected to the conductive member, and including an automatic potential controller; wherein a potential difference between the positive and the negative terminals of the external DC power supply is set in order to generate oxygen in seawater while suppressing generation of chlorine in seawater.
