thanks, but No, electrons always move from anode to cathode in both cells, it's just the "signs" of the anode and cathode are revesed. in galvanic anode is (-) and cathode is (+) and in electrolytic anode is (+) (the picture is wrong, it has a (-) in the anode of the electrolytic cell) and the cathode is (-) in electrolytic cell.
but actually I was not asking about that, I was asking about the difference between "current flow" and "electron flow" , for example, in the concentration cell, examkrackers book says nature wants to create entropy so the current flows from the more concentratd side to the less concentrated side and electrons follow accordingly, which I think means that electrons flow in the same direction as current.
but I checked my text book under the concentration cell and it says that electrons flow from the less concentrated to the more concentrated side,
so is the electron flow opposite or the same as the current flow??
