 adequately gas exposed palladium would remove traces O2 from your industrial h2 by instant catalytic recombination H2+O2>H2o.or you could just float some platinized asbestos fluff ontop electrolyte.

Voltage recovered back to +146 but then dropped to 8. Even opening to oxygen only raised it back to 150. Something screwed up, I think, after passing the 6v. no time to check today.  I will try plating gold for the next test.

 carbons are very unpredictable pomodoro it takes long time to equilibrate due to van der waals.tell me something before you plate gold,is that glassy C patch rough or smooth and is that 0.1microamp that mark E is refering to at the base of the  discharge curve or top

Smooth.  There was basically no current out of this. 0.1 I saw just for a split second. It did discharge because the volts dropped to zero.  Area is quite small, diameter is probably 3-4 mm. I have no more industrial h2 for other tests.

At least you proved that the chinese laborarory tests are consistent with reality.smooth glassy carbon at 4mm is minuscule surface area but it should be ok to make out voltages.plate that gold thick pomodoro,we don't want any interference from the underlying carbon.use wetting agent,ammonium sulfate added to your h2so4 for this next test.sulfuric sol does not wet surfaces well.

Make sure that your gold-plating solution has wetting properties otherwize we'l get micro-patches exposed carbon

I think your palladium was slightly poisoned after you induced electrolysis btw pomodoro.a tiny bit sulfate ion reduced all way to H2S creating that dip anomaly.this is why I'm against any hydrogen production from sulfates. H2SO4 + 8H+ + 8e- > H2S + 4H2O. 0.3v

I need to re palladise my electrodes,   cells, even in alkali, are not responding well when oxygen is reintroduced. Don't ask me how anyone can seriously test these cells at home. It seems oh so easy on paper, but so much goes wrong.
I may end up using some clear plastic test tubes to make fused electrode, sealed versions of the Pd/Pt NaOH Cu hydrogen cell and call it quits if it dies.

Try cathodizing hectic in NaOH to drive sulfides back into solution and restore activity in the same manner as silver is cleaned from Ag2S pomodoro.use a cheap graphite anode

Don't call it quits before you have built and tested my suggested pt(black)/pt(etched) air/o2 karpen to fanaticaly convert you into a karpen believer.

Don't worry I promise to do that before I leave. Look I don't disbelieve anything, let's let a perfectly executed experiment determine the truth. So far I'm skeptical but not looking to destroy the theory.

This test shall be done after I finish with the hydrogen. What voltage differential do you expect to see.

Similar voltage to my pt(-)/Ni(+) air experiment.anything between 0.1-0.2v. A lot depends on your platinizing skills.if you use manufactured platinized pt foil definitely 0.1 and up.use high impendance v-meter for stable reading or large pt foils with a normal digi v-meter.you'l get around 50micro-amp/cm2 in bursts.

Have a look in this picture.here is another spontaneously reversed potential against the standard table.2Ag + CO3-- >< Ag2CO3 + 2e-.. -0.47v (standard)/MnO2 + 2H2O + 2e- >< Mn(OH)2 + 2OH-..+0.05v(standard) .this is because O2 gas kinetics faster on MnO2 catalyst as opposed to silver catalyst.this will not work under argon.
