An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). The word was coined by William Whewell at the request of the scientist Michael Faraday from the Greek words elektron, meaning amber (from which the word electricity is derived), and hodos, a way.
Electrodes are essential components of electrochemical cells as the movement of electrons across them through oxidation and reduction produces an electric charge. Since they need to be good conductors of electricity, they are usually made of metal and are commonly used in fuel cells, electroplating and grounding.
