Under "Galvanic cells compared to electrolytic cells" it says that "a galvanic cell must use dissimilar metals" but this is not true. A galvanic cell could also use the same metal but with different ion concentrations in solution, or maybe even with only a difference in the solution medium (ionic strength, complexing agents, etc.)
The point is that the galvanic reaction is caused by different electronegativities of the metals to the ionic solutions, using the same metal limits the usefulness of the difference in electronegativity, there is more info on the
galvanic cell article and if you wanted to raise this point on that talk page it would be more appropriate there.

The "Cells" section is off topic because it is not about electrolytic cells but about other types of electrochemical cells. It could therefore appear in a "see also" template at the top of the artcile.
