I use stainless steel sheets for my cathodes
Since theyre not emitting anything they are fine for this purpose. ...
I have tried the carbon rod, from the center of a
carbon-zinc battery, but it got plated with silver so I
reversed the connections, occasionally, to unplate them.
After that, I just use similar silver electrodes, so I can
reverse the current, periodically, to cut the rate of silver
loss from either, in half.
I think, with a stainless steel electrode, you have to be
careful of polarity and use strictly DC to drive the
process, or you risk getting iron, nickel, chromium,
manganese etc. in the solution. With two silver electrodes,
this cannot happen, regardless of current direction.
