plate spaceing

[kbwakesk8]

has any one figured out the optimal plate spacing?

[lhazleton]

It depends on the active plate area. In my experiences, smaller plates (< 30 or so sq.in.) seem to work well with 1/16" gaskets, while plates with larger active areas are better off with 1/8" gaskets.

[kbwakesk8]

is this a function of resistance and current

im planing on have large plate areas

by increasing the gap your raising resistance lowering current draw but keeping voltage the same.

i read a while back but cant find it it talked about watts per area in a cell

Im a mechanical engineer by trade so i over analyse every thing and before i build any prototypes i run all the numbers first.

It seems like one of the variables has to be conductivity of the solution. I dont know if there is such a table for example conductivity of KOH (if thats what you are using) in water at certain concentrations at certain temps... I suspec the numbers would even vary then with temperature change.... Sounds like a lot of variables are at work to try and come up with a formula... Ahh... Thermo...

im trying to use straight water then i can calc out the resistance of water.

my plates will have to be much closer together.

i am putting together a formula to maximize hho

Im going to run a very long pair of plates rolled together.

as a spirole in a wet cell but have 6 cells in total .

with a total surface area of about 100 square ft.

working it all out on paper before i build.

??? OK, so you're going to use 2 long plates rolled into a spiral?:confused:

like this as an example.

maximize surface area

I knew it... You're going to need to make 7 of them, well at least 6 anyway. The separator material may be problematic, as the bubbles need to migrate upwards. That is UNLESS- and I just had this idea so it's mine! mine I tell you!.. er, sorry, -unless you start the spiral on a capped plastic tube (obviously just one end is capped :D) then the length drilled with holes so that electrolyte can be pumped through the tube into the beginning of the spiral and then around and around until it emerges along with the gas bubbles. This presumes you plan to use spacers that run parallel with the roll, otherwise perpendicular spacers would cause continual changes in plate spacing and make hot spots.
Since you're going to do this thing, why not order a couple rolls of nickel200 shim stock, it's already got a curvature built in... Man I wish I was doing this one!:cool: PICTURES!

[lhazleton]

That's what I thought you meant.

DAMNIT GUS, QUIT POSTING AT THE SAME TIME I DO!!!
I swear, you've got some kind of 6th sense or something.

I'm sorry Lee, I'll try to never do it again:(:(:( ....................................:rolleyes:

I surely do not want to discourage anyone from trying this but been there done that. The flow problems, spacing problems, are very complex. I did get it to work but because of both flow and spacing irregularities it was not even as efficient as a normal open bath reactor, much less a sealed circulating reactor. I hate to think of the money and time I spent on that baby. LOL I guess some one with a lot more money, time and smarts could figure it out. Each unipolar set of winds have to be in their own container and then wired in series. Space is another problem. Well just rehashing all the problems in my head is giving me a headache. After all the time and money if you do get it right you come back to the same thing. You can only get so efficient with brute force. That is it so why not keep it simple. There is no holly grail even though I keep looking. LOL

i have a lot of friends in the metal working industry and i also studied manufacture engineering and processes in school.

stainless coils

is what im looking at using.

and a hundred more!!!

I told you been there done that. Not a single one of those are what would be called an efficient reactor either. Good luck.

What are some bench mark numbers

L per amp

amp per plate area

what are people truly maxing out at

what is the ranges of a truly efficient cell

Sorry im a numbers guy.

Well that is a loaded question to me. My answer is based on brute force no added energy of any kind.

For gas not having all moisture taken out 125 watts or less per LPM.

For gas having all the moisture taken out 172.5 watts or slightly less per LPM.

Because of some very recent data I am unable to state what I would call accurate information regarding amps per square inch of active area. This is being tested but will require a number of weeks and possibly months more. The current rule is between .25 to .5 amps per active area on one side of one plate in a bipolar reactor.

You being a numbers guy must know you can twist them around 7 ways to Sunday to get them to say what you want. Build it and test it is the real answer. Like I always say 1+1 has two answer 2 or 11 just depends on your point of view. You can tell I am not a numbers guy.

[kbwakesk8]

thank you
now when i get ready to test i have a bench mark judge against
