Abstract

Plural composite panels are aligned in multiple horizontal rows. Each composite panel includes a titanium panel (anode), an electrical insulating member and a stainless-steel band member. The titanium panels (also, stainless-steel band members) of horizontally adjacent panels overlap each other to be in face-to-face contact. The stainless-steel band members are horizontally connected at different levels to form long negative electrodes (cathode) extending in seawater-flowing direction in an inlet channel. Each stainless-steel band member is exposed to seawater through a gap between vertically adjacent composite panels.
