KARPEN PILE

[profitis]

Etched iron even larger area

 submerged nickel vs Pt foil in alkali an astounding 0.04v with the nickel as cathode(!)Not anode.

@sarkeizen.all hydrogen encapsulated experiments require excessive knowledge,skill and experience.all air oxygen experiments require none of the above.therefore we conclude all oxygen air experiments in this thread to be 100% consistent with karpen expectations and repeatable by anyone.

Here is my latest test.  Massive surface area steel wool.

Steel wool , degreased in dichloromethane, etched iin dilute HCl, washed many times with deionized water.

Newly prepared palladized platinum, 1M NaOH , UHP hydrogen.

When initially fired up, volts rise to +500 mV wrt the Pd/ Pt electrode.
Discharge through meter is huge, peak well over 10mA, and discharge goes over many minutes at over 1mA.

A lot of this is due to any oxygen still in the cell and any oxides that formed on the steel wool.  Cell is shorted  now out for over 12 hours to force all oxygen and oxides to reduce.

Please see video of the very initial discharging. A followup will be posted after the overnight discharge.

The meter peg is impressive.
