The geometric parameters determining the distribution were the interelectrode gap, electrode length, transverse section and length of the electrolyte manifold. These results are useful for estimating the performance of the stack. The current distribution becomes more uneven when the distance between the electrode (Anode-Cathode) increases or decreases. however comparing the parts of A and C, show prominent current distribution only at small in deviated position of A and C. It can be observed that an increase in electrode gap has changes on current distribution and Throwing Power [TP] and also on current Efficiency [CE] as decreases, the effect of interelectrode gap on the current distribution is more pronounced than effect of electrode length. This study showed that the effect of interelectrode distance on the rate of metal deposition on a cathode can be satisfactorily described by the model.
