| The tank will be fitted with copper and ferrous anodes which are fed with an electrical current from a control panel. |
| Some materials commonly used as unreactive anodes are platinum and graphite. |
| The cartridge anodes are preferably plated with a mixed metal oxide such as iridium oxide and ruthenium oxide to catalytically improve the production of oxygen. |
| Our second dive is on this historic submarine, so that Mike can check anodes placed to reduce corrosion of the now-delicate hull. |
| In addition, unlike chloride ions, which form chlorine gas, carbonate ions are not corrosive to the anodes. |
| The materials that are useful for anodes must be good conductors and must not corrode too easily under oxidizing conditions. |
