Try not to bend,touch black foils when assembling,this dislodges coating

Ok, the weekend experiments were no good.   The gadget #3 only recovered to 40mv. I shook the flask and it rose to 350. Shorted and got over 1mA peak. And left it alone. It only rose to 95mV in an hour.  On inspection it no longer had any positive pressure, but a very slight vacuum.

The graphite as expected lost all power.

So now #3 is back with some improvements as you can see in video. 
1.Electrolyte is lower in volume, allowing Pd into gas phase.
2.Purging of electrolyte went on for 10 minutes  - Voltage dropped from 900mV to around 500
3.Tygon tubing used all round
4.Exhausted hydrogen passes through water trap
5. After 10 minutes trap is sealed off, allowing a small pressure buildup of hydrogen from cylinder regulator. A tiny leak is allowed to purge a very small amount of hydrogen through system

If this don't work I don't know what will!!

Pomodoro you are going above and beyond in  your efforts.  Hopefully, this latest appraoch will yield interesting data.

Cheers markE!

Very early days, but for the last few hours it is constantly supplying 20uA at 117mV, stable, through the 50 uA galvanometer.
Lets see how looks toorrow.

If its stable tomorrow we have something to work with.

Yes this is the best way to do it pomodoro.hydrogen is a bitch! If it remains stable at 20micros I can assure you it will leap up near or past the one milliamp area when well rested.0.5v sounds about right(remember the chinese 0.45v).did you test a piece silver pomodoro?
