Hi Jetijs,

I have been following your inspiring work for some time now. Since you show some interest in electrolysis stuff, I would like to share some of my experience on high efficient low voltage electrolysis. So far I find Bob Boyce design works best for brute force (direct dc) method which could easily break Faradays law on electrolysis efficiency. In order to do that, just follow strickly on Bob's suggestion like space gap, material used, electrolyte strength and so on. Read http://www.panaceauniversity.org/D9.pdf as reference.

What electrolyte are you going to use for your cell? KOH or NaOH? KOH not suitable for polycarbonate. NaOH not suitable for acrylic. KOH performs better than NaOH in terms of LPM vs efficiency. The best cell gap for series cell is 3mm between plates. Best electrolyte strength for 3mm gap series cell is 28%(KOH) or 23%(NaOH).

Only disadvantage for series cell is on electrolyte refilling. My 8 plate series cell works very well with high efficiency rate (above 100%) and able to produce 1.2LPM using 14V and 10A. I wanted to get at least 2LPM using 12V and 10A. So now I'm focusing on pulse DC and frequency for electrolysis.

You may want to refer my hobby work on 8 plate series cell.

I feel you need very much higher strength electrolyte for each compartment since the gap is wider. Check if the cell can pass through 10A below 15V. I would suggest remain 3mm gap per cell with one neutral plate in between.
