KARPEN PILE

[pomodoro]

Before I start fusing glass to metal, I'd like to try using good grade epoxy, no less than 1cm thick to seal electrode wires within drilled glass stoppers.Hydrogen will be tested with pb nitrate and a slight positive pressure kept within the cell. No continuous flow this time.

Okdoke.use copper,gold,silver wire through the seal just enough to get through to inside and twist tight onto direct leads.I'm estimating 0.4-0.6v overpotential dif.try not to allow capture of air before sealing or vaccuum will form and puncture gadget2

Heres an oxygen based karpen cell test utilizing two different fuel cell oxygen catalysts,silver and MnO2.note the power relative to the size of the cathode MnO2 crystal (1mm by 2mm cubed)30-40microamp.both surfaces have been treated for surface area.electrolyte is 1M NaOH.voltage is 0.1v at top discharge curves(actualy one interrupted curve shown).contact wires made of nichrome(contributes less than 0.5microamp)

I've nearly finished the electrodes, will post a picture tomorrow.  How did figure an emf difference of 400 mv?   You have the same conc of protons and partial pressure as the Pt electrode.

If gold gives 0.45 then Ag will give around the same pomodoro.its just power that we need to get from it.
