KARPEN PILE

Found cell very weak, frothy electrolyte and the silver electrode had the gray deposit easily wiped off. For now going to try copper with stirring and no bubbling of hydrogen.

Copper cell being shorted is allowed to recherge and discharged through 6kohm galvanometer

Focus on the Pd/Ag Ni/Ag pomodoro,success is certain with those 2.its just a matter of playing around til u get it right.we must try get back to 16uA constant bottom of discharge.that is already indicative of total success.reanodize-cathodize the Ag in Na2CO3 for more surface area.your experiment with copper is expected  to be weak power.

I need stability for a start. Silver is losing power for whatever reason. If Cu is stable I can tinker with it and tackle Ag again. I tried carbonate treatment. Worked very well initially but again failed overnight.

All of these cells should theoreticaly lose power all way down to a few micros on constant short-circuit discharge.its the accumulative wattage at the top of a well rested cell curve that matters most from a practical pov.I see your palladium is a bit too much underneath electrolyte in this experiment but at least some is exposed.I see you didn't blacken your copper either but ok this just to chek 4 stability.
