Hello everyone! I have been an active reader on this forum, but until today have not yet posted. So here we go:
I have built a 31 plate dry cell unit to produce hydrogen in a 97 Jeep grand Cherokee Limited (5.2l v8) The cell itself measured 6x6x4.25 inches and the 314 stainless steel plates are 5.5" wide (.036" thick). Each plate has three equally spaced half inch holes drilled through them for circulation (vertically as in a top hole, middle hole and bottom hole looking at the face of the plate). I used standard 1/16" thick O rings that measure 5.25" wide to just fit inside the area of my plates. The endcaps/plastic plates are .75" pvc. The cell has two bottom water/electrolyte solution inlets (one on each side) and two upper gas outlets (one on each side). The tank for the electrolyte solution is a standard one that can be found in many hho builds and serves as both a resivor for water and bubbler for hho gases. From the main tank, gases flow into a small pvc secondary bubbler before being routed to the engine (into intake right before manifold). For my electrolyte solution, I currently use KOH mixed as a 10% solution with distilled water (about 12 tbsp of KOH to a gallon of water).
Electronically, I routed wiring directly from the battery (in parallel with main connection) to a relay, so the ignition of the Jeep turns on the generator, a 30 amp in line fuse, an ammeter, a voltmeter, a toggle switch, and a 30 amp generic (ogo) pwm. (Not exactly in that order) It then runs to the generator where I then get 1.6 to 1.85 volts in between plate gaps. (Again, 31 plate 5 neutral. So 3 positive hookups, 3 negative hookups and 5 sets of 5 neutral plates) When the cell warms up, I can consistently run the generator around 16-18 amps which is with the pwm maxed out. For whatever reason, I could never get more amperage through the generator, which kind of makes the pwm useless since its supposed to be to put more current through the generator until it gets warmed up, but yet I can only get like 14 amps when I tun it on cold (pwm maxed).
Anyway, that is my setup, but here is my problem: With all of this, I can only get about half of a liter per minute of gas production. I feel as though I've seen generators half the size of mine making 2lpm so I'm stumped. Previously, this generator was a 19 plate cell with 1/8" O rings that I upgraded to what I have described. Although the production increased, it is still far from great... I have spent tons of time on this and have read almost everything I could find, attempting to build it the right way. I have tried more concentrated electrolyte solutions, and hooking the generator straight up to a 12v battery with no other components to no avail. 1/2 a liter per minute... is this all I can get from this setup? I don't know what I could be doing wrong... I've checked to voltage in between each plate, checked the seals on the tanks, and just about everything I can think of... I am a junior in high school and am truely commited to getting this working so any help would REALLY be appreciated I just don't know where to go from here...
Also, I took a quick video of my setup so you all can see everything that I'm talking about.
