Hello uziao.
We can see the cell behaving like a capacitor below the 2V.
Get a milliamp meter, and an good precision adjustable power supply.
Rise the voltage like 0,25 or 0.5 at a time, you will see the milliamps climb up as you rise the voltage and come down again, until you reach the 2v marks.
Also, if you use a signal generator and an oscilloscope across the cell, you can observe one thing:
You will get a pure dc voltage below 2v threshold, above that, you will have the signal you put in (eg. square wave) and it behaves like a resistor.
If we want to get further on this technology we need to forget about the patents and other stuff and learn by experimenting and observation, Meyer did not gave everything in a silver plate to everybody out there, and don't assume everything he says as the full truth, he was not that stupid to give his work for free.
