KARPEN PILE

You might want 2 try blacken silver in HCl aq but you must cathodize hectic and rinse dam fast(hot water) to avoid re-oxidation in air exposure.its possible that the black layers were loose and actually insulating our silver from electrolyte,most of my success came from grey spongey adherent coats.your prior method of discharge of a h2/ag2o cell seems best way to get adherent coat

Chek if you get a precipitation with KOH vs NaOH I've got a feeling of bicarbonates forming(CO2 impurity frm your H2 ) which will salt out of concentrated base.just bubble ur gas straight thru respective bases in a beaker.chek if the mystery nuisance precipitate dissolves in excess h2o this will give massive clue

Copper test was a success.  Nothing changed overnight. Electrolyte still clear,  1ma meter gets slam dunked after recovery.
Nickel plated copper but got much smaller voltage and weak current. Its too similar in characteristics to Pd with H2. Stripped off Ni  and plated pure Ag. So far a bit better than Cu but not greatly at equilibrium but has more punch when discharged. Perhaps other silver electrodes were impure, hence the ppt.  I know plated metal is not going to last but using it for short term tests.

Exellent pomodoro.I think its our surface prep of silver that's messing us around.etch that silver in HNO3,rinse,then shove it into next test(don't anodize-cathodize)it will be stable.main priority now is just stability.keep the copper experiment going meantime let's see what happens..

Don't jump anymore between experiments when we have stability.let's put the test of time now..
