The original patent used a pair of platinum plated titanium electrodes, 3" square. When running it, they occasionally reversed polarity to maintain the best environment for the electrodes.
My plan is to use an MMO mesh anode surrounded by two solid plates of CP titanium for cathodes, all 4" square, which should work nicely. I hope the added size will more easily get to and operate at a high enough temperature to reach and maintain a running temperature of about 110o
C, which should optimize the production of NaClO3
while concentrating the electrolyte by evaporating the excess water, making chlorate recovery at room temperature
(rather than chilling the electrolyte to 0o
C for oxidizer recovery, as done previously) a much simpler and less costly process. An added benefit will be using purified brine to recharge the "depleted" electrolyte, rather than dry purified salt.
The whole system appears that it will easily lend itself to a continuous system, but baby steps first.
