An electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy to force a chemical reaction that would otherwise not occur. [ 1 ] : 64, 89 [ 2 ] : GL7 The external energy source is a voltage applied between the cell's two electrodes ; an anode (positively charged electrode) and a cathode (negatively ...
An electrolytic cell is an electrochemical cell in which applied electrical energy drives a non-spontaneous redox reaction. [5] A modern electrolytic cell consisting of two half reactions, two electrodes, a salt bridge, voltmeter, and a battery. They are often used to decompose chemical compounds, in a process called electrolysis.
Electrochemical cell, a device which produces electricity through chemical reactions, commonly referred to as a battery; Solar cell, a device which produces electricity from sunlight; Electrolytic cell, a device which decomposes chemical compounds through electrolysis; electric cell can convert chemical energy into electrical energy
The Downs cell uses a carbon anode and an iron cathode.The electrolyte is sodium chloride that has been heated to the liquid state. Although solid sodium chloride is a poor conductor of electricity, when molten the sodium and chloride ions are mobilized, which become charge carriers and allow conduction of electric current.
Diagram of the mercury-cell process, showing an "inner" cell sandwiched between two "outer" cells, with a layer of mercury common to all three. In the mercury-cell process, also known as the Castner–Kellner process, the "outer" electrolytic cells each contain an anode immersed in brine, which floats on a layer of mercury. The "inner" cells ...

Proton exchange membrane (PEM) electrolysis is the electrolysis of water in a cell equipped with a solid polymer electrolyte (SPE) [3] that is responsible for the conduction of protons, separation of product gases, and electrical insulation of the electrodes.
A galvanic cell consists of two half-cells, such that the electrode of one half-cell is composed of metal A, and the electrode of the other half-cell is composed of metal B; the redox reactions for the two separate half-cells are thus: A n + + n e − ⇌ A B m + + m e − ⇌ B. The overall balanced reaction is: m A + n B m + ⇌ n B + m A n +
