TECHNOLOGY FOCUS - METALLURGY - Preferred Metal: The metal is chosen from magnesium, magnesium alloy, titanium oxide, sulfur, zinc, zinc alloy, 80 tins/20 galvanized steel, galvanized iron/steel (galvanized sheet), aluminum, cadmium plated steel, aluminum/manganese alloy, soft iron, duralumin, tin, lead, brass, chrome-plating steel, soft solder, and nickel chrome plating on steel, copper, copper alloy, silver solder, austenitic stainless steel, nickel plated copper, silver, rhodium bas gold plated copper, silver/gold alloy, carbon, activated carbon, gold, and platinum. The electrode inserts cloth, resin, and charcoal cloth between the spaced-apart electrodes, stacked electrode and a parallel electrode. The voltage and electric current generates from electrode purification component and can be electrically stored, and an electrical double layer capacitor can be discharged. The metal electrode incorporating the genus from which an electromotive force differs may annihilate the biocenosis adhering to the living organism, the microorganisms, and ship body which are present in the ballast water of boats and ships as a motive power which generates electrochemical reaction by an electrode potential, and generates electric-field and static electricity, and exhibits antimicrobe and antimold. Preferred Microorganism: The movement of microorganisms are barred by the electrodeposition phenomenon which attracts the metal ion has an electric charge of an opposite symbol for the living organism and microorganisms which float in air and water to the cathode of an electrode, and forms an electrode film in an electrode surface, and is called a metal-plating phenomenon, and anti-microbe and anti-mold are exhibited by crevice. The electrode purification component contacts based on the presence of water vapor, air, when the component immersed in water, discharge occurred, generated electrolysis of water and it separated the molecule of water (H2O) into the hydrogen ion (H+) and the hydroxide ion (OH-). The antimicrobe and antimold are exhibited by destruction of the cell membrane with respect to hydronium ion and hydroxyl ion to the free radical, and discharge of an electrode surface. The metal area with a low electromotive force from which an electrochemical-potential column differs is larger than the other said metal area. The one side of metal is arranged in a surface of cloth, resin, or charcoal cloth. The other side of metal is arranged in the other surface of the cloth or charcoal cloth. The metal is at least one formed in a lattice form, mesh, or spiral form to the cloth, resin, or the surface of charcoal cloth. The one side of metal one is arranged such that the metal may be surrounded by the other metal. The cloth, resin, or charcoal cloth in which metal was formed was formed in the cylinder shape. The electrode purification component comprises microparticles electrode in which the metal electromotive forces differ. The microparticles electrode is coated by ceramic coating. The electrochemical reaction is generated by coating and an electrode potential.
