Hi Bob. I'm using silver for the cathodes too for simplicity's sake,
and since I've got plenty of the wire on hand. What's different is the
surface area of each. The coin I'm using for the anode has many times
more surface area than the combined cathodes.
See the attached sketch of the electrode arrangement.
I'm not planning to use polarity reversal on this setup except possibly
intermittently as a trick to keep the cathodes clean or to stir up the
ion clouds. What I'm really hoping is that simple diffusion and
convection will be enough to accomplish that.
Current density will be around 200uA/sq.in. at the anode, at the
cathodes about a hundred times more. (Not taking into account edge
effects or other field distortions.)
Wasn't there some strangeness we talked about a year or two ago about
the effects of differing surface area?

Thank you sir!
Be well,
