Daniell Cell vs. Galvanic Cell: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 21, 2023
A Daniell cell is a specific type of galvanic cell using copper and zinc electrodes. A galvanic cell is a device that converts chemical energy to electrical energy via spontaneous redox reactions.
Key Differences
Both the Daniell cell and the galvanic cell have an essential role in electrochemistry, serving as foundational concepts for understanding spontaneous redox reactions and the conversion of chemical energy into electrical energy.

The Daniell cell, named after John Frederic Daniell, is a specific type of galvanic cell that employs copper and zinc electrodes submerged in their respective sulfate solutions. This setup results in a predictable voltage under standard conditions. In contrast, the term galvanic cell refers to a broader category of electrochemical cells that produce an electric current through a spontaneous chemical reaction.

The primary purpose of the Daniell cell is often educational, showcasing fundamental principles of electrochemistry in classroom settings. However, the galvanic cell, given its broader definition, has extensive practical applications, ranging from batteries in everyday devices to advanced energy storage systems.
