n: 1. one of two electrodes in an electrolytic cell;represented as the negative terminal of the cell, it is the area from which electrons flow. In a primary cell, it is the electrode that is wasted or eaten away. 2. in cathodic protection systems, an electrode to which a positive potential of electricity is applied, or a sacrificial anode, which protects a structure by forming one electrode of an electric cell.

the positively charged site in a cell. Oxidation site. The site of metal loss in corrosion.

n: a primary cell, such as a flashlight battery, in which the electrolyte is a paste. The term dry" is misleading, because moisture is necessary for the electrolyte to function.

n: a unit that produces electricity from the chemical reaction of conductors of dissimilar metals through an electrolyte. In a primary cell, the chemical energy has its origin within the cell, and the chemical reaction is not reversible. Also called a voltaic cell. See dry cell, wet cell.

n: see primary cell.

n: a primary cell in which the electrolyte is a dilute acid.
