An electrochemical cell that uses a spontaneous chemical reaction to do work. Also known as a voltaic cell.
A cell consisting of two dissimilar metals in contact with each other and with a common electrolyte (sometimes refers to two similar metals in contact with each other but with dissimilar electrolytes; differences can be small and more specifically defined as a concentration cell).
A device consisting of two compartments separated by a porous plug or salt bridge. One compartment contains the anode immersed in a liquid or semi-liquid medium which bears the reductant (reducing agent), and the other the compartment contains the cathode immersed in a medium which bears the oxidant (oxidising agent). In the anodic compartment, the reductant is oxidised. In the cathodic compartment, the oxidant is reduced. The galvanic cell runs spontaneously in the direction that produces a positive cell potential. Electrons flow through the external circuit from the anode (negative terminal) to the cathode (positive terminal). Anions flow through the porous plug or salt bridge into the anodic compartment to balance the positive charge built up there by oxidation, and cations flow into the cathodic compartment to replace the positive charge lost there by reduction.

an electric cell that generates an electromotive force by an irreversible conversion of chemical to electrical energy; cannot be recharged
a cell in which current flows, power is produced, and the cell reaction is proceeding spontaneously
a device constructed so that a reductant and oxidant are physically separated, but connected by an external circuit made of a conductor (to carry electrons) and a salt bridge (to carry charged ions in solution)
a fairly simple device consisting of two electrodes (an anode and a cathode) and an electrolyte solution
an electrochemical cell in which chemical energy is converted into electrical energy
Electrochemical battery that store electricity.
a device in which chemical energy from a spontaneous oxidation-reduction reaction is changed to electrical energy that can be used to do work.
An electrochemical cell in which a spontaneous reaction occurs. Such a cell can be used to generate electricity. Also called voltaic cell.
A cell in which chemical change is the source of electrical energy. It usually consists of two dissimilar conductors in contact with each other and with an electrolyte. or of two similar conductors in contact with each other and with dissimilar electrolytes.
A combination of electrodes, separated by electrolyte, that is capable of producing electrical energy by electrochemical action.
A cell, consisting of dissimilar metals in contact with each other and with an electrolyte, which generates an electrical current.
An electrochemical cell for which the cell reaction as written is spontaneous. It thus produces electricity as a result.
The Galvanic cell, named after Luigi Galvani, consists of two different metals connected by a salt bridge between the individual half-cells. It is also known as a voltaic cell and an electrochemical cell.
