No gold. I might be able to plate gold.  Look I'm willing to try one more test, just one and it needs to be something related to these hydrogen cells and that is documented as being done by karpen. Are the above docs any good. What hydrogen cell is being talked about and what voltage or current did he get. No more fooling around with un documented systems.

You read my mind pomodoro (-:. Yes absolutely strictly along the lines of successful document tests from now on.my french really sucks but I could make out that pressure tends to raise potentials in hydrogen capsules.he got about 0.160v between black and smooth Pt at normal pressure and 0.7v under pressure if I'm not mistaken.he revealed nothing about other metals that I can make out there.the 1956 document is of extreme interest because it specificly names gold,which is also what the chinese tinkered with.I suggest gold plated onto glassy carbon surface(non porous) and afterward briefly etched in aqua regia.a hot boiling rinse in sodium carbonate sol will be required after etch to remove adsorbed chlorine gas and HNO3.you will have to plate quite thickish.I suggest the use of ammonium sulfate for electolyte in the karpen battery as opposed to the sulfuric which they used.ammonium sulfate is mildly acidic and has the advantage of lowering surface tension in solution much like bases do(its solution wets surfaces).dilute sulfuric acid does not wet surfaces.

You will have to be extra cautious about air leaks this time because O2 potential drasticly larger in acidic solutions.

The chinese after 10months playing with a sealed Pt(black) and smooth gold got an totaly stable 0.3v in H2SO4 aquaeous.other electrolytes they got higher or lower voltages.they got stable volts with Pt(black) vs Pt shiny too.

Neither karpen nor the chinese mentioned anything about current.that is up to me and you to maximize.

Well the pt black vs pt I can do back at work with no more expense. What conc sulfuric , hydrogen pressure and expected voltage did the Chinese get. I really want to replicate this cell as close as possible to the smallest detail. I would personally only expect ultra small voltages only. If you are worried about secrets then send the exact details to my email and all I will report here is if it worked or not without exact details.

While I'm waiting on profits, anyone know French and can translate the 3 pages?

Leave the Pt(b)/Pt alone pomodoro.do the Pt(b)/gold setup please and report only voltage here(not current) in the same manner as karpen did and as the chinese did.

Do this setup in the gadget at atmospheric pressure please and with ammonium sulfate(1M) not H2SO4

Here is the carbon electrode I'll be using.

Test number 01

Pd/Pt  (my best electrode) -

 Air -

 magnetic teflon coated  stirrer -

Polished, Ethanol washed,Glassy Carbon electrode (note only a small area is the carbon black body is plastic) -

1N A.R. Sulfuric Acid in MilliQ purified Water.

Purpose of this test is to see how it behaves in air.  Cell will be shorted out for 12 + hours

Video shows emf of fresh  cell, Pd/Pt electrode connected to ground termnal,  ie: carbon is negative 50 mV with respect to Pd/Pt.

Impedance of meter is 10^12 ohms, electrode processes should reach equilibrium, however any tiny impurity on electrodes will affect emf until cell is shorted for a long period of time to reduce/oxidize them.

Nice. Pt/glassy C in air followed by Pt/glassy under H2 pomodoro? Followed by gold coat in air vs H2?

Have a look at the monster overpotential of glassy C vs Pt for h2.. 2v!  http://en.m.wikipedia.org/wiki/glassy_carbon
