To provide for essentially uniform current density at the respective cathodes of an electrolytic cell, a plurality of cathodes are located, spaced from each other, at one side of an anode, and resistance elements connect the respective cathodes to a negative supply terminal or supply bus (N, 11), the resistance elements having respective resistance values which decrease as the distance of the respective cathode from the anode increases. A single anode (2), preferably separated from the cathode space (5) by an ion exchange membrane (6), can be located centrally within the cathodes; or two anodes can be located spaced from each other with a plurality of cathodes located therebetween. Each cathode is connected with a quick disconnect plug-or-push terminal to the respective current supply, which may be a controlled constant current source.
