"The metal ions themselves must be prevented from moving between the electrodes, so some kind of porous membrane or other mechanism must provide for the selective movement of the negative ions in the electrolyte from the right to the left."
I honestly don't understand how can the Zn2+ and Cu2+ move between the half cells. Secondly, if the salt bridge is not present, I understand that excess positive and negative charge will build up. This means that the potential difference between the 2cells will increase and thus the current flow decreases. is this correct?
