Title: which is the best electrolysis chamber design?
Post by: rickhunter7 on June 23, 2007, 01:03:33 AM
Greetings.

I am about to embark my self in some hydrogen generation experiments and I want to build my own electrolysis chamber. I have studied many designs that I have seen through the web and I am confused as to which is the best to try. Some of them suggest that you divide oxygen from hydrogen, some of them take both gases together, some suggest pulsed energy some don't.

What do you recommend? What are the differences, pros and cons? did I spell electrolysis right?

Just look out for neutral plate designs...
Most of the time nutral plates act as resistance,
lowering the amperage and HHO production rates.
Now some people will tell you lower input means its
more efficient but according to most of the lab notes
I've read by different electrolysis researchers: they
stated the increased amperage is far outweighed by
the hydrogen production achieved. Both designs are
still under unity, but non neutral plates do work faster.

Good luck,

Howdy rickhunter7;

Welcome to the jungle.

What design to use best?  Depends on yer end use, to an engine or thermal process immediately, or storage for use later.

HHO, the comingled H2 and O2 off a neutral plate design, is pretty much useless to store- you cannot safely store H2 and O2 in its stoichometric ratio.   It's best to send it to a flashback preventer, then immediately put it under vacuum on its way to the process.

To build an electrolyser that can produce copius amounts of hydrogen and oxygen, separated from the start, also requries copius amounts of money.   The proton exchange membrane design will get you there, but nafion (the actual membrane) is only pennies cheaper than gold, by weight (Or so it seems).

What do you want the gas fer anyway?  Fuel cells require pure H2, but if y'all got the change fer fuel cells, you probably wouldn't be here on this board.

An engine doesn't care if O2 comes along with the H2... the dangerous ratio disappears the moment the gas hits the air intake.

I've built flat plate, concentric tube and bipolar (not manic-depressed) designs.  Currently working on the most efficient ways of powering them, as Dingus mentioned.

Hello everybody and thanks for the answers.  :D

I forgot to state that I want the hydrogen to power a car engine, so what I'm trying to get is a system that can be powered by a car's battery efficiently enough to keep it running.

About the neutral plate stuff, I must confess my ignorance, what is it? I don't expect you to tell me, just tell me where to read about it.

Thanks a million.

hey rickhunter7; how about you come over too the hho thread started by Ironhead...we are starting to get the move on building and everything that goes along with it....read it all....on pg14 there is a great example of a Neutral plate series cell.
Should help answer some of your questions.

High voltage HHO is an excellent place to start.   By the time y'all get that thread read I'll have that second hi-power urethane cell cookin' with gas.

Dingus, ya challenged me, brother!  I'llbuild a sister cell to the 19 plate neutral plate cell, to set up series-parallel, same size plates, 5 sets of four... that way I can compare output straight up, amp for amp, litre for litre.

That probably won't get done this week, but I got the parts in hand.

Man, this is a great way to spend "golf time"!

Good to hear Turtle!

It's been done a few times before, but I firmly belive in reconfirming results!
PLEASE POST HERE! (lol) Have you thought out the electrode assembly yet?
You can offset every other plate and use a SS bolt on each side to create a
series cell, and then remove the bolts and you have neutral plates. That way
you can test both cells with one cell! I'll post link with a video example.

Good luck on your experiments!
