KARPEN PILE

[profitis]

Mmm @markE.I don't have any palladium sponge lying around but I'l see what I can seal up in a straw for a lil demo.it was pomodoro who said he may or may not with-hold info at will in the beginning of this thread.

Sorry about the late reply but I just came back from the patent office. I'm winding up these hydrogen karpen cells but as promised will try out the Pt black vs Shiny Pt in air very soon. Will post results ad soon as I have them.

 ok pomodoro let's see your plat-air results etch the bottom one please

[pomodoro]

Ok top one is etched and  platenized Pt other one is etched Pt. Electrolyte is 1M NaOH.  Left them shorted 24 hrs and I let them charge up overnight.

I'm going to put both up on top near each other and see if a potential difference still develops.

If you got no impurities in your plating process then both submerged will drop in voltage.both at top will also drop in voltage.you can even use 2 identical black foils for this test or two identical smooth foils and get same result.two platinum wires cut from the same piece will also give same result.raise your top one higher for more voltage
