Sebos,
i once tried to pulse the cell and then extract the charge back, by using an EEC.
That worked well. But all the charge you extract from the cell made also less gas.
It all stays a basic electrolysis proces. Just keep as much charge as you can in the cell and you will have the most efficient electrolysis cell.
The idea of charging up the cell, like a capacitor is good thinking, however, you can do it easier with first charging up a capacitor and then hit the cell. No gains in such a system either, as far as i have seen.
If you could raise steadely the voltage in your cell by some kind of dc resonance or whatever system, then maybe you can achieve the catastrophic electrolyte breakdown, ,we all searching for...
Stans famous stepup charging would be great to do so......
But all stepup charging is a time delayed consumtion of current and voltage.
Maybe a breakdown triggers other molecules and then we might get a higher efficiency we are all looking for.
