Quick update. Pd/Pt vs Cu. Worked well after 3 days. Decided to try a cheaper version for building a higher voltage pile. Now trying Palladized Cu vs Cu. Also now using uhp hydrogen. I'd like to be able to power a device constantly, these cells discharge ultra quickly. Any ideas on microamper motors requiring a volt or so, or a pulsed milliamp motor that keeps spinning till the next discharge some 30 seconds later?
A synchronous P MOSFET switch into a capacitor would do the trick.

Thanks marke  will look into that soon. 
Profitis  any chance that the power from this device is the double layer charging to the Ag reduction potential and discharging when connected to the lower voltage of the Pd hydrogen/ proton couple?

No pomodoro.there's definitely h2 coming out the cathode(you can't see it,bubbles are too small and diffuse rapidly away)all passage of faradaic charge must be accompanied by redox reaction otherwise electroneutrality is violated.its just catalyst spillover from textooks.

Lol @sarkeizen..ever tried to seal hydrogen gas in a leakproof bulb with 2 wires sticking out of it? I thought not

What's the status pomodoro?? So we have stablility for Pd/Cu,Pd/C,Pd/Ag correct??

Relax @sarkeizen it won't be long now.what you can do in the meantime is quickly build my other design  under the threadname 'perpetual batteries by vasilescu karpen' for a direct violation of the second law thermodynamics.

Cheers for link, I'll have  good read of it later on today.

The stage I'm at is testing  the pure Silver foil instead of the wire or plated copper.   


Need to make sure the system is steady for a few weeks before I make the permanent totally sealed in glass version.

Well things are not going too well. A nice polished and solven t washed silver cathode in 0.1m na carbonate does very well initially but after discharging for 2 hours recovers very slowly    and each time the voltage is always weaker. Silver is still nice and bright. Intake the electrode out for a second and when I put it back all is good again, for a while.  I'm starting to think that the cathodes that worked had slow to react oxides from the anodizing process which can power the device for a long period of time.  :-\

0.1m sodium carbonate is too weak.its pH is much weaker than the KOH so anode voltage dived and cathode voltage rose.you must use concentrated Na2CO3 if you do use it. Its possible that you did leave some oxides of silver in samples but its also possible that hydrogen buildup was too much in the layers that were too black and fine.you have to anodize your Ag briefly,cathodize it shitless for thin grey-black adherent layers that won't cause H2 buildup blockage.

If you can get for the silver what you got for the copper for 3 days it is safe to seal pomodoro.all traces surface oxides wouldve been obliterated after about 1 hour shortcircuit.obliterated by the shortcircuit AND obliterated by direct exposure to H2.

Do not be impatient after longrun shortcircuiting.sometimes what happens is voltage climbs back up fast and current buildup lags behind slowly,then after a certain Pd/H2 saturation point current recharges fast.if you've discharged for a few hours,let it rest for a few hours.

Back to basics. 1m naoh fresh Pd/pt silver plated copper. Uhp h2. Shorted for the night. Let's see in the morning.

Ok pomodoro.meantime please try get hold of a piece solid pyrolusite,we can build a nice potent oxygen karpen for the viewers meantime
