Meaning and Definition
An electrochemical cell that generates an electric potential from differences in concentration of the same electrolyte on its two sides.
More broadly, any system where a difference in concentration of a substance drives a process, such as diffusion or osmosis.

FAQ
Frequently Asked Questions
It is an electrochemical cell that can produce a voltage, similar to a battery, but it is not typically used as a practical, long-lasting power source. It's more a demonstration of a principle.
The voltage is driven by the tendency of the system to reach equilibrium. Ions move from the higher concentration half-cell to the lower concentration one, creating a potential difference.
Yes, corrosion in a metal pipe containing water of uneven oxygen concentration creates a 'differential aeration cell,' which is a common type of concentration cell leading to localised rusting.
Because the voltage depends logarithmically on the concentration ratio. Unless the concentration difference is enormous, the resulting voltage is relatively small, often just tens to hundreds of millivolts.
An electrochemical cell that generates an electric potential from differences in concentration of the same electrolyte on its two sides.
Concentration cell is usually highly technical / scientific in register.
Concentration cell: in British English it is pronounced /ˌkɒnsənˈtreɪʃən sɛl/, and in American English it is pronounced /ˌkɑːnsənˈtreɪʃən sɛl/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of a cell (like a battery) that's concentrated on one thing: a difference in CONCENTRATION. It's a cell powered by concentration inequality.
Conceptual Metaphor
A BALANCE seeking equilibrium: The cell's voltage acts as a force trying to balance the concentration difference, like a scale tipping until weights are equal.
