Galvanic cell is an electrochemical cell which converts chemical energy of the redox reactions into electrical energy. It consists of two half cells, oxidation half cell (anode) and reduction half cell (cathode).
Oxidation half cell involves loss of e- and reduction half cell involves gain of e-. Thus redox reaction takes place.
In redox reactions, e- are moved from one species to another. If the reaction occurs in a spontaneous manner, then chemical energy is released which is used to perform useful work.
