What does increasing the concentration of an electrolyte solution on the potential difference of a galvanic cell, and why does it do that?

Basically, it does not change the potential. However, there may be a small effect owing to the change in the ionic strength and the activity coefficient of the electrolyte. This has to do with the fact that if you increase the concentration of the electrolyte in water, then the water becomes a little less like water.

Note that when the potentials for the half cells were developed, it was for a specific concentration of the materials. Going either side of the concentration may produce slight differences in voltage due to dissociation in the water. You can actually make a cell using different concentrations of the same materials in each of the two beakers. It is a common problem of corrosion when you develope a concentration cell and so called stainless steels are chewed up, not by the chemical stored in it, but by the electrochemical reaction.

I have no freaking idea
