Daniell Cell vs. Galvanic Cell — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on December 26, 2023
The Daniell Cell is a specific type of Galvanic Cell using copper and zinc electrodes; a Galvanic Cell is a generic term for devices that generate electrical energy from spontaneous chemical reactions.

Key Differences
The Daniell Cell is a historically significant electrochemical cell, introduced by John Frederic Daniell in the 19th century. The Galvanic Cell, on the other hand, is a broad category that encompasses all electrochemical cells that convert chemical energy into electrical energy through spontaneous redox reactions.
In a Daniell Cell, the anode is made of zinc (Zn) and the cathode is composed of copper (Cu). When the cell operates, the zinc electrode dissolves into the solution while copper ions get reduced and deposited on the copper electrode. The Galvanic Cell, in its generic sense, refers to any set of electrodes and electrolytes that can facilitate similar spontaneous redox reactions, but not necessarily limited to zinc and copper.
The uniqueness of the Daniell Cell lies in its specific construction, where a porous pot or a salt bridge is used to separate the two half-cells, preventing the mixing of solutions but allowing the flow of ions. The term Galvanic Cell, meanwhile, can be applied to various cell designs with different electrodes and electrolytes, serving as an overarching term.
One key reason the Daniell Cell is of historical importance is its role in the development of early batteries and the understanding of electrochemical processes. The Galvanic Cell's significance is broader, representing the foundational concept of harnessing energy from chemical reactions in numerous applications, from batteries to corrosion prevention.
