There are 6 sections in this HHO generator, each one has five stainless steel 304 plates. The middle one is the negative, the outer two plates are positive and the remaining plates between the positive and negative plates are the neutral ones (this is needed to test out some joecell concepts). The sections are wired in series. I wanted to run this setup with only 12V (about 2V for each section), but I did not use enough electrolyte to get enough amps, so I increased the voltage. Will add more electrolyte on the next test, because is takes some time to take the lid off with all those bolts 😀
If I will be able to get this baby draw enough current on just 12v, there wont be any heat problems. I am using KOH as electrolyte. The flashback arrestor with the fine bronze wool works just great.
