Right @mark E.the experiment proved beyond reasonable doubt a willingness for the palladium/mercury/NaOH/H2 battery to spontaneously self-recharge without outside interference in the same way that oxygen spillover devices do.let's see what pomodoros latest test reveals.let's wait for more data.

Ive leaned from these experiments to expect failure later on.  In this setup, there is no real positive pressure as I am using the spout of the cylinder for the entrance of the wires. Its only a small gap but its still a gap and although the hydrogen is flowing out, some air could be coming in. 

The mercury is quite deep in the cylinder and I would expect the bubbling hydrogen to purge a lot of the oxygen out but who knows.  The upper Pd/Pt is succeptible to air and its strange behaviour in low hydrogen flow may be due to a little air entering the cylinder on top.

Lets see what the Platinum down there does.   There is very little hydrogen dissolved in water but perhaps enough to for a couple with water on the Pt.  Mercury dislikes hydrogen, so the activity of hydrogen is lower on its surface. 

The reduction  potential on the Pt shoud be around -0.83V  for H2/H2O/OH- in 1M NaOH. This will be quite accurate in the cell.

that for Hg/Hg2+   is +0.85 but in standard conditions, so here it will not be that, but will be a mixed potential which will include the sum of the above hydrogen couple. how much influence any of these have on the actual potential will depend on their kinetics ie: current densities.

Any oxygen will raise its potential substantually.

If there is a positive outcome in a few days, when I got back to the lab, a sealed version will be made.

So in my books, it looks positive, although it has no power, but I will need to completely seal it to be sure.

I don't understand mr pomodoro.you choose to tell us about this airgap concern only now? And introduction of a second wire doesn't increase your chances of air inflow? and why are you getting the standard electrode potential for mercury in alkali completely wrong? It is exactly -0.098v for HgO + H2O + 2e- >< Hg + 2OH- with a thick paste of mercury oxide mixed in with the mercury,which as you know is totaly and utterly completely absent in your mercury metal.all invisible surface oxides should be virtually wiped out off that mirror surface in seconds on mere exposure to H2.forgive me but I'm going to be harsh with criticism

Please note mr pomodoro, I've already declared your mercury/palladium experiment a success.I want to see if you can follow up on this now.

Dear profitis no need to apologize. All criticism is more than welcome. If the cell looks good in a few days, then a version which will be completely sealed will be made.
