I have built my first HHO generator and I'm stumped as to a problem I'm having.

I'm only getting bubbles from the the electrode + and - plates and no production from any of the neutral plates.

I have two 7 plate cells (six water cells each). + N N N N N - - N N N N N +

All production is from the 2 + plates and the 2 - plates.

I'm using KOH for the electrolyte and added it in small amounts until I was drawing 20 amps cold. I'm producing a liter of HHO in 1Minute 20 seconds cold (about 80 degrees). As it runs and gets hotter (about 130 degrees) the amperage gets as high as 28 amps.

This is a wet cell generator and the plates are 16 gauge SS 7-3/4" X 2-3/4". They are spaced 1/16" apart.

My goal is to generate about 1-1/2 to 2 LPM of HHO running between 12 and 18 amps using a CCPWM to control the amperage.

From the results I'm getting my goal doesn't seem unrealistic since I'm producing the 1 LPM with only 28% of the plates working.

I've tried reversing the cables but the same production conditions exist.

Why are none of the N plates producing anything?
