So you beg me to not bother with the oxygen karpens when I came on here and now you keep babbling on about some cowpat that gives power for a million years. You are a strange man profitis

Given the difficulties associated with hydrogen containment yes I shouldve just gone with the air flow first pomodoro.its not too late to make ripples here mate.we can make micro-history with a full-blown double plat-air device what say you pomodoro. This time we get desired results correct first via pms before hopes goes down the drain due to error/delays/disputes what say you?

Pomodoro seems to have managed to get the hydrogen set-up free of O2 intrusion that you insisted upon and his results so far have not supported your hypothesis.  I think Pomodoro is perfectly justified in expressing his frustration that the tests you insisted upon have consumed a great deal of his time and money, and that now you want to go in a completely different direction on his time and nickle.  What hard data can you produce that would motivate Pomodoro or anyone else to pursue further test of your ideas?  What is there to show that what you propose now would be anything more than the sort of "tinkering" that Sarkeizen has so vocally criticized?

Hard data? Lol @mark E.do you actually understand what I'm asking pomodoro to do.I'm asking him to shove two platinum electrodes into base or acid and get perpetual power from it in a very definite direction,cathode ontop,anode submerged.in line with what we expect from the nernst equasion and oxygen concentration disparity

Profitis, this thread documents very well what you have and have not done.  If what you ask of Pomodoro is so trivial and the results so important, one might rightly point out that you should have done this long ago.  Yet, the best we get from you is a dirty bottle cap.

Let him decide @mark E.the viewers are really keen to see if it will work (-:

I don't attempt to speak for Pomodoro.  Again, if what you ask is so trivial and so significant why is it that you have not done it?  Why hasn't anyone else done it?

The big deal is that:  You have made extraordinary claims that you have not evidenced.  You have insisted that certain experiments if done by others would support your extraordinary claims, but when Pomodoro went to great lengths and expense to conduct experiments that you dictated, the experiments failed to support your claims, and now you insist that different experiments are needed.  It should be plain to see how frustrating it should be to Pomodoro that because he gave you some credit he spent a lot of time and money on what you now declare was pointless.  It should be plain to see that what you have dropped your credibility to a new low.  I can't imagine a prospective employer seeing how you have conducted yourself giving you any serious consideration for a position.

Are you saying that the two-platinum system will not give power and current @mark E

  BTW Im not going to do any tests if they require electrolysis,  these will of course show hydrogen overpotentials!
I cant modify the original message, so I'll keep pasting the original, with additions.


-----------------------------------------
Air Karpen    Pd black on Pt vs Glassy Carbon  in 1N Sulfuric Acid.


I've just unshorted the cell, after 18 hours  and will report hourly emf of cell.  I'll keep modifying this post rather than creating new one, so keep coming back here for the updates.

negative value  means C is more negative than the Pd/Pt

Time   EMF
 0 -    0mV
1hr    -1mV
2hrs   -8mV
3hrs   -12mV

Voltage does change very slowly. Decided to end experiment here, now passing UHP hydrogen through exacltly same setup.  Cell is shorted out

-------------------------------------------------

Hydrogen Karpen, same setup as above, but flushed with constant UHP quality hydrogen

Notes:   Pd/Pt  electrode in 1N H2SO4 now becomes essentially the well known NHE electrode.  Normal hydrogen electrode found in all text books.  Very fast response / kinetics. Large exchange current . In other words, any stray oxygen gas has very little effect on its voltage as it is swamped by the fast hydrogen/proton reaction.  We need to focus on the other electrode to explain strange behavior. Forget about this electrode!

As soon as hydrogen was introduced, the voltage immediately rose to a healthy +800mV.  The carbon becoming the cathode, with reduction occuring at its surface.   This is very easily explained by remembering that any residual oxygen has little effect on the Pt electrode but will  give rise to a mixed potential at the  Carbon.  The hydrogen/proton kinetics are very slow at the carbon, so its potential will be a mixture of the oxygen redox and the hydrogen redox potentials,  the onw with faster kinetics will dominate the reading. 
Anyone repeating these experiments must remember that oxygen, or oxides on the surface  will fool you into believing you have a huge potential.

After a few hours of shorting out the terminals, to reduce  any oxygen reaching the Carbon, the short was removed and the voltage monitored, here are the results as measured with a 10^12 ohm electrochemistry style voltmeter.

Time         mV
30 secs    +26
1 min       +40
5 Min        +96
10 min     +118
40min      +137
70 min      +147

This is much slower than when the cell is shorted immediately after the hydrogen is first passed, an then unshorted.  In this case the voltage rose to +800mV in 15 seconds!

eighteen hours of shorting out later, and here are the results

Time       mV
30s        +8mV
1 min     13 mV
12 mins   +70mV
50 min     +122
1hr 50m   134
2h:50 min   141
4h:20 min   146
5hrs            +146

Conclusion,  after equilibrating, cell seems to show a potential difference of 146mV, with the carbon electrode taking on a positive voltage. 

Unless the cell is sealed completely, it is impossible to know if a trace of oxygen from the hydrogen which is being constantly bubbled through the cell has any influence on this voltage.

less than 0.1uA flows when shorted.

I then deliberately use a 6v cell and placed it across the electrodes for 3 seconds ,  visibly producing hydrogen at he carbon and oxygen at the Pt.

The voltages across the electrodes are now -1200mV, I'm planning to see its recovery

Yes, this forum locks out changes after awhile.  I think it is about a day.

0.1uA is a pretty small short circuit current.

Excellent result @pomodoro. Proves a dead-stable 0.146v.it sounds about right for carbon systems.the chinese only got about 0.07 v for a different type of graphite vs Pt not Pd.you see now clearly the importance of shorting,then relaxing, before getting its real voltage

The one thing I don't like about carbons are that they tend to cling to gases quite long after a rest period.van der waals forces hold onto gas quite stubbornly,I wonder what diamond would do.

You should retry your industrial hydrogen vs uhp in the same setup,same waiting period and see if it differs.you should also try with an electrolyte additive that wets surfaces like ammonium sulfate
