Investigation of the secondary current distribution in a hull cell

A new equation of secondary current distribution of the Hull cell is derive d which can explain the influence of some electrochemical kinetics and mass transport on the quality of electrodeposit, and can give some instructions for the electroplating using indirect current and for the study of seconda ry current distribution in a modified Hull cell. The results from the theor etical equation and experimental measurement are compared with that of othe r experimental formula. It is shown that the result from the theoretical eq uation is more suitable to the actual conditions than that from the empiric al formula.
