5.1.2   Corrosion Cell

 

The corrosion cell is an electro-chemical reaction that involves the flow of electricity (the transfer of electrons) from one metal to another metal. It occurs through a solution (a.k.a electrolyte) capable of conducting electricity such as seawater, wet soils, or moist air. The corrosion reaction results in oxidation and reduction, and the classic example of this cell is the automobile battery or flashlight battery shown on the next page.
