KARPEN PILE

[profitis]

Ok  pomodoro you can handle it (-:. Work with me please.don't tinker.leave the tinkering until you are finished with live experiments.viewers get confused.our main focus was and now definitely is very specificly that palladium sponge vs mercury potential.anything else is distraction.

No problemo, I'll work on another bung design that will allow positive pressure like the previous setup.

Continuous flow please pomodoro.Make sure that the end exhaust pipe is under water for pressure and to act as oneway valve.I don't trust any static systems because they cannot purge airleaks. the ideal exhaust rate is about one bubble every 2 seconds.

Use a singlestrand jacketed copper wire for your mercury connection

Ok folks,  this is my latest attempt at a profitis cell.    We have the setup that you can see in the vid below.  Triple distilled mercury is at the bottom of the cylinder. Above it is a magnetic stirrer which I might use later.  In the mercury is a a copper wire, prepared as  seen in the picture. Melted glue prevents any water from seeping up the wire strands.

Up on top is the palladized platimum electrode.

UHP hydrogen is bubbled through the liquid , and pressurises the space between the bung and the electrolyte, which is 1M NaOH (AR) in MilliQ water.  The hydrogen comes out of the cylinder and bubbles through a water 'valve'.

The flow of hydrogen is higher than normal as I have just set the cell up and want to remove oxygen quickly. Its flow will be lowered later.

Voltmeter shows volts of mercury wrt Pd/Pt.   Later cell needs to be shorted to make sure all reducible species are reduced by the hydrogen.

Success will achieved if tomorrow and even later, a healthy voltage still exists between the two metals.
