Electrochemical cell

A demonstration electrochemical cell setup resembling the Daniell cell. The two half-cells are linked by a salt bridge carrying ions between them. Electrons flow in the external circuit.

An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or using electrical energy to cause chemical reactions. The electrochemical cells which generate an electric current are called voltaic cells or galvanic cells and those that generate chemical reactions, via electrolysis for example, are called electrolytic cells.[1][2][better source needed] A common example of a galvanic cell is a standard 1.5 volt[3][better source needed] cell meant for consumer use. A battery consists of one or more cells, connected in parallel, series or series-and-parallel pattern.
