The anodic layer, the cathodic layer, the DC power supply unit, and water together form the conducting path for water electro-catalysis. Hydrogen and oxygen gases are produced to form a thin gas film on the submerged surface to reduce friction and prevent biofouling on the carrier. Alternatively, the apparatus produces hydroxyl radicals to kill marine microorganisms and reduce the risk of biofouling and biocorrosion.Type: ApplicationFiled: April 30, 2014Publication date: November 13, 2014Inventors: KEE-RONG WU, YU-TSUEN SHYU, CHUNG-HSUANG HUNG, JIING-KAE WU, CHIUNG-WEI YEH, SHUN-HSYUNG CHANG
