A galvanic cell is an electrochemical cell in which spontaneous redox processes occur which allow the continuous flow of electrons through the conductor, while redox reactions are induced by an external source of current in an electrolytic cell. The mechanical energy is transformed to electrical energy in a galvanic cell, whereas the electrical energy is converted to chemical energy in an electrolyte cell. Here, in the article, let us learn more differences between galvanic and electrolytic cell. Given below in a tabular column, the difference between electrolytic cells and Galvanic cells is listed neatly.
Galvanic Cells vs Electrolytic Cells
|Galvanic Cells||Electrolytic Cells|
|Spontaneous redox reactions convert the chemical energy to an electric energy||Non-spontaneous redox reactions convert the electric energy to a chemical energy|
|Electric energy is generated by redox reactions||Electric energy brings about the chemical reaction with the help of an external source|
|The cathode is the positive electrode and anode is the negative electrode||The anode is the positive electrode and cathode is the negative electrode|
|The process of oxidation takes place at the anode and the reduction process occurs at the cathode||Here, the oxidation process occurs at the cathode while the reduction process takes place at the anode|
|Half cells are set up in different containers and are connected through salt bridges||Electrodes are kept in the same container in a molten or solution electrolyte|
|Application lies in Batteries||Application lies in purifying copper and electroplating|
From the above differences between galvanic cells and electrolytic cells, we can conclude that a galvanic cell produces electric current with the help of the chemical reactions that occur spontaneously in it, while an electrolytic cell does the opposite, that is, it brings about chemical reactions with the help of an electric current from an external source.
