The approach presented here demonstrates an energized system that provides cathodic protection and biofouling control that could eliminate anti-fouling hull coatings. Results from immersion panel testing of a variety of electrocatalyst materials and a small-scale Jon boat prototype – as well as experimental measurements of the electrocatalyst material efficiencies and models of oxidant concentrations – were used to design a 1/8-scale prototype installed on a 64 foot Navy research vessel based out of Panama City, Florida. The prototype design was carried out through computational modeling to solve a system of partial differential equations describing the coupling of electric current conservation and mass and electric species transport. The prototype underwent exposure testing for eight months. Regular diver surveys and system data collection monitored the system's effectiveness at maintaining the hull potential and keeping the hull free of biofouling.
