A voltaic cell (also known as a galvanic cell) is an electrochemical cell that uses spontaneous redox reactions to generate electricity it consists of two separate half-cells a half-cell is composed of an electrode (a strip of metal, m) within a solution containing mn+ ions in which m is any arbitrary metal.
Electrochemical or galvanic cell “electrochemical cell or galvanic cell is a device in which a spontaneous redox reaction is used to convert chemical energy into electrical energy ie electricity can be obtained with the help of oxidation and reduction reaction. An electrochemical cell is a cell in which chemical energy is converted to electric energy by a spontaneous electron transfer in the case of the potato, the zinc in the nail reacts with the copper wire. But they aren't the only kind of electrochemical cell it is also possible to construct a cell that does work on a chemical system by driving an electric current.
