Usually, in most cell designs, the concept of two-electrode design is the baseline. The two electrodes are anode and cathode where the electron transfer happens between them. However, I have been reading about 3 electrodes and 4 electrodes designs where the new electrodes are used to control the potential while allowing the working electrodes to deal with the current transfer. However, I wanted to know how to control the potential of my cell and what is the equations for that if I want to build my own multi-electrode cell.
Thank you
