Some silver will plate out on the negative electrode. Using a silver negative electrode allows you to recover the plated out silver for use.

Correct me if I am wrong, but absolutely NOTHING physically comes off of the negative terminal during production, right? The only thing that comes off would be electrons reacting with water molecules or incoming silver ions or a few amount of contaminant cations. I'm wondering if the ideal gen has a lot of surface area on cathode also. If so, copper would be preferable so you don't pay for all that extra silver. Hey, could that also make a gen that doubles as a colloidal copper setup? What do people use colloidal copper for anyway? ~David On Wed, Sep 8, 2010 at 6:01 PM, Dan Nave <bhangcha...@gmail.com> wrote: The cathode (in this case the negative terminal) can be copper if you are not polarity switching.
