A model is presented for a parallel plate electrochemical reactor which has electrodes that are the same size and are close together. That is, the distance between the electrodes (S) is much smaller than the length (L) or width (W) of the electrodes. Consideration of the material balance equations in light of this small aspect ratio (S/L) condition leads to predictions of derived quantities of interest (e.g., current efficiency) that depend on the product of the aspect ratio and the Peclet number, where Pe = 2VavgS/DR. Predictions of such derived quantities are made for electrolysis of an aqueous, hydrochloric acid solution containing copper in a cell with no separator.
