Does size matter?

Right, now that I have your attention.

Lets say we have this configuration.

+nnn-nnn+ Stainless steel 316 grade. Same electrolyte for this scenario, be it sodium hydroxide or potassium hydroxide or baking soda.

Now we are successfully pumping 15A@13.8V through the plates and they are spaced 1mm apart.
Now my question is this.
Would making the plates a foot square versus 6 inches square make a difference to the amount of hydrogen being created?
I say no because it is the amount of current being passed which creates the hydrogen....but I could be wrong.
Also what about the thickness of the metal? would it make a difference.
Someone said after a few experiments .9mm 316 stainless was the best producer for him.

I put it to the you...the avid hydrogen creators of this forum...what do you think?

I think more surface area would help some because one of the major limiting factors on production is that the bubbles stick to the plates which causes the plates to loose surface area for production. It is documented on the web that part of the efficiency lost is due to bubbles not releasing from the plates. check out this patent: http://www.freepatentsonline.com/7014740.html. Its my opinion that making the plates larger will yield better production.

I have finally set up a decent ammeter although its range is only 20A.
Turns out I am producing about half a liter of HHO per minute at 20A.
Not good enough by any means.Imagine the current draw at 1LPM of HHO.
I am running +NNN-NNN+ a nine plate arrangement and the plates are 143mm deep by 66mm wide and 1mm apart. needles to say I am a bit disappointed.
I must admit I have not insulated the 1/4" stainless steel supply rods yet or used a decent electrolyte. Damn baking soda is getting to hot for my liking.
Can't wait for my Potassium hydroxide to turn up.
I might try a smack booster arrangement next. Except I will use my 316 Stainless without the bent edges as I cannot purchase those wall plates here in Aussie land.
Maybe I need to paint the edges with something to prevent current leakage as well.
I need to stay under my 30A self imposed limit for this.
I guess this is what it is all about...trial and error.
has anyone looked at those Alexis cells yet. 2.2LPM at 18A sounds too good to be true.

I'm not big on the neutral plate thing.

One thing I do know is that the more N's the more HHO

Hydrogen is made on the negative side so you need to have -nn+nn-

every n drops your cell volts and amps down by about 1.5 to 2 volt and proportional current each. Spacing also effects this.

Good luck.

Hydro is right hydrogen is made on the neg. plate and the oxy is made on the pos. from my exp. the more neg the better

Now don't take this wrong. You say you aren't big on the Neutral plate thing and the next sentence you say that the more N's = more HHO. 'N' and 'n' being the same thing, you lost me.

I think 1mm gap is too close. 3mm or 1/8" has been found to be optimum.

Plate size does matter. 2-4 square inches of plate area on every face is recommended for each amp of current for optimal performance according to Patrick Kelly.
