How about use Nickel-Brass for Cathode and Hastelloy C2000 as Anode ?
The electrical Conductivity of these Metalls is much better than SS 316.
With this we could use a non-caustic Electrolyte like Potash and Soda Ash. 50/50 Mixture.
WE have been using 316L for the past 6 years now and the plates show little signs of degradation of the metal. If there is another metal better suited, we do not know about it.
