I am trying to refine my CS generator. There is a lot of silver plating out as grey sludge on the cathode. I would like to find a way to minimize this.
I use 3 Maple Leaf coins 3/4 submerged as anodes and a single stainless steel cathode approx. 1/2" x 3 1/2" x 1/16" in a 1500 milliliter container with a switching power supply starting at 20 volts & I manually lower the voltage to maintain about 1.5 to 2 milliamps current. Does the size of the cathode make a difference? I thought that using a smaller cathode might leave less surface area for the silver to plate out, but would this affect the current?
