Hull fouling will increase the resistance of the ship while driving, and the increase in fuel consumption will also cause hull corrosion. Electro-Catalytic electrolysis of seawater to produce chlorine (Cl) or hypochlorite ions (ClO-), strong oxidizing forces to eliminate bacteria and micro-oganism, inhibit the growth of micro-oganism, the low voltage electrode method is applies direct current, the use of low voltage electrode method transfer electronic and catalytic between the hydroxyl radical, destroy or reduce the adhesion of microbial, inhibit the parasite of microbial mucosa. This study explores commercial dimensionally stable anode DSA (Dimensionally Stable Anode, DSA), known for good conductivity and excellent corrosion resistance, potential application to biofouling prevention. The use of DSA has a good conductivity, excellent corrosion resistance. Simultaneously, DSA itself processes the use of non-toxic gases and substances, effective to inhibit microbial attachment, and does not destroy the marine ecology. The experiment of this study places firstly immerse uncoated blank titanium and DSA sheets in seawater, for observation of marine growth. Electro-Catalytic DSA in seawater is performed at 0.7-0.8 V vs. SCE, which is determined by initiation of gas evolution of the electric catalyst. And then select the appropriate voltage (DSA0.7~0.8V). The experi-mental results show that, uncoated and non-powered titanium sheets immersed in seawater for 10 days began to grow hydroid and algae. The electric-driven DSA shows no biological growth for 30 days in seawater, proving the feasibility of DSA to prevent hull fouling.
