KARPEN PILE

[profitis]

How much chloride ion can leak through this salt bridge in the middle of this ref electrode.that is the question.

The junction has KNO3.   In any case the main problem is oxygen. There is a video which I have not uploaded as yet that shows the  Ag karpen charge up to 900mv as soon as the hydrogen bubbler is removed and air allowed entrance .
The next karpen will be smaller, kept shorted ,sealed with visual means of observing a positive pressure inside it from the hydrogen.

Ok.If we can just get the same V that the chinese got with Pt/Au(not Pd in their study paper) 0.45v and at least one mA/cm2 and permanent.. Then we can pop the shampaigne corks.you now see how difficult it is just to contain H2 without a leak.you also now see how impossible it is if one doesn't know ones electrochemistry quite thoroughly.experience and knowledge are necessary.

Reference KNO3 wouldve also caused probs,its an oxidizer.

 a U-bulb like this with borosilicate is easy if you have a lab.you can cntrol how much H2 you want sealed by size of bulb at the anode.the cathode side is last to be sealed with gas burner.this can be done very easy with plastic instead of glass.
