I'm researching methods of using HV for electrolysis for the production of hydrogen. I've uncovered several techniques, but am interested if this fine group can tell me of techniques utilizing HV to produce hydrogen. Thanks in advance. CM

1 way I like to think about is using two high temperature conductive screens about as big as a penny and a quarter inch apart immersed in water and then pulsing them with a high voltage/high current from high capacity,high voltage capacitors,
yes?..... I think so

let me know if you get an arc hot enough "2300 centigrade" to split/combust the water. I am very interested and it would help my efforts immensly as I have no experiance with capacitors. I am mostly mechanical

I've been working on some ideas about HV electrolysis for a while, the closest things I've seen on the net are usually called plasma electrolysis. The main problem I foresee is that high voltages encourage arcs, which would be bad around hydrogen.

My initial ideas centered around having a couple of stainless steel screens close to one another in a pipe with high pressure steam flowing through them. With the screens charged to a few thousand volts there'd be plenty of plasma to hopefully split lots of steam into H2 & O2 / HHO / browns gas. But you would want to be very certain of having enough steam to stop any arcs, otherwise you'd get bad bangs.

I have to say I haven't tried this, I'm only really just starting on building electrolyzers....and they've all gone bang on me so far (scrounging too-cheap parts).

I have heard HV does assist in electrolysis and I have also heard that pulsing (AC) at 20k+ hertz has helped in the electrolysis process. The only problem is I have never tested either so it is purely speculation as of now.

hi guys. im new here
i found a website which might interest you
i dont know if youve heard of bigno fuel
if not, here is the website:

i havent read the entire content of the website
this reactor uses 30volts AC (high amps)
its not high voltage but it produces an arc just like a high voltage would.
the water used has a little mixture of fuel.
but if you just want to split plain water with the plasma or arc
go to "how to build a cheap and simple aquafuel generator"

http://jlnlabs.imars.com/bingofuel/index.htm

so what do you think?

Watch the videos... No fuel needed!

If you can't find the right valve here's a link to order one.

They claim to never have flashback problems.

Using a fuel cell will get you 80% efficiency with minimal heating, which makes more sense then combustion. IC hydrogen engines are only 30% efficient due to heat, sound, and hydrogen leaks. Hydrogen molecules are so small even a combustion cylinder is not leak proof, so even a one way water valve will only partially inhibit back flow to the bubbler. American Antigravity has been developing a multi fuel vehicle that uses hydrogen combustion. They're method for overcoming this problem was simple. Seal the liquid fuel input on the carb or injector, then use a large diameter length of tube for the air input capped with a air filter. Near the manifold drill a tiny hole in the air tube for input of hydrogen, and feed it to the engine with a variable regulator. Any back fires are minimal in strength because of the minimal resistance offered by the air filter and lack of oxygen in the hydrogen input line. Good luck with your work, but please take some time to research fuel cell technology as efficiency is what engineering is all about. Also check out the thread on "Dr Linnard Griffin's hydrogen on demand unit", electrolysis is going the way of the dinosaurs...

My current testing, with no chemicals to say in the cell I made. 12 volts with frequencies from up to 40Khz (I have not tried under 4Khz yet but will today before I re-program the microcontroller). But 4K-40+Khz and no change in gas production.

Next test will be change duty cycle and see what I get. If no change in production, I was going to add a boost power supply and see what I got (ranging the frequency and duty cycle again all over again).

I have a lot of H and O2 coming out, not enough to run a 5HP 4 stroke motor (well I can not seem to get the gas in the manifold without problems..

Biggest problem I have is gas in the line from the bubbler keeps blowing up the bubbler. And $10 for a one way value at an air conditioner parts store I passed not knowing how good it would work on this type gas.

So I went back to a cup of lite soapy water, watch the bubble per second and then light them. The bubble count and ringing in my ears is my testing method for now. Sounds like an odd way, but until I get a one way gas valve. My kids loved the bubbler blowing up though (they were a long way away but heard and saw it without a problem).

I think I may have found the part you need to save you next bubbler from failing.

Its too bad too hear about your bubblers, but it made for a great story.
Hope everyone was ok though! Please keep us updated on your research.

http://jlnlabs.imars.com/bingofuel/index.htm

so what do you think?

This uses 30v AC to create a plasma underwater, and the carbon rod
erodes to give H2 and CO. Naudin claims 400% over Faraday electrolysis
production figures, and has the gas drving a Honda Generator, but it
not clear how much power it is generating.
An interesting process. The sacraficial carbon electrode is a nuisance.
Presumably, if stainless steel electodes were to be used, then H2 and
O2 might be given off.
