Galvanic Cell vs Concentration Cell

[jessicaosuna_1F]

Hi! Can somebody please explain the difference between a galvanic and concentration cell? Thank you in advance :)

I was also wondering this but when I looked it up, it seems like a concentration cell is a type of galvanic cell so I'm confused. I know that concentration cells are made of two half-cells, each containing the same electrodes, but different concentrations. The whole point is to establish equilibrium by transferring electrons

A concentration cell is made of two half-cells with the same electrodes but different concentrations of chemical species. This is done in order to create a concentration gradient of electrons wherein an equilibrium is reached through the flow of electrons. Through this flow of electrons, a redox reaction occurs.

Galvanic cells have the flow of electrodes from anode to cathode without adding an electrical current. In a concentration cell, there is the same aqueous solution in different concentrations, with the cathode containing the higher concentration, and I believe it is a type of Galvanic cell as mentioned above :)

Galvanic cells are the ones that have electrodes flowing from anode to cathode without an electrical current whereas in a concentration cell, they would be in the same aqueous solution but have different concentrations.
