KARPEN PILE

[profitis]

Do this setup in the gadget at atmospheric pressure please and with ammonium sulfate(1M) not H2SO4

Here is the carbon electrode I'll be using.

[pomodoro]

Test number 01

Pd/Pt  (my best electrode) -

Air -

magnetic teflon coated  stirrer -

Polished, Ethanol washed,Glassy Carbon electrode (note only a small area is the carbon black body is plastic) -

1N A.R. Sulfuric Acid in MilliQ purified Water.

Purpose of this test is to see how it behaves in air.  Cell will be shorted out for 12 + hours

Video shows emf of fresh  cell, Pd/Pt electrode connected to ground termnal,  ie: carbon is negative 50 mV with respect to Pd/Pt.

Impedance of meter is 10^12 ohms, electrode processes should reach equilibrium, however any tiny impurity on electrodes will affect emf until cell is shorted for a long period of time to reduce/oxidize them.

Nice. Pt/glassy C in air followed by Pt/glassy under H2 pomodoro? Followed by gold coat in air vs H2?

Have a look at the monster overpotential of glassy C vs Pt for h2.. 2v!  http://en.m.wikipedia.org/wiki/glassy_carbon
