By better designing the cathode surface to make it more wettable and inert to the aluminum pad a better contact can be achieved between the aluminum pad and the cathode surface. If this happens the ACD can be reduced thus decreasing the voltage drop and hence resulting in energy saving. The wetted drained cathode provides these properties 18 .
