Ways to increase MMW...

[lhazleton]

That looks better. However, your current density is still a little high (.52A/sq.in.). It should never be over .5A. If you increase the apmerage to 30, your current density is going to shoot up to .93A/sq.in., thus losing efficiency.

So right now at 15 amps it is at the best MMW it can be at? I noticed that if I add another N plate the voltage / gap is at 1.9 and it will only draw about 5 amps max, so I guess I have achieved the best that is possible with my lowes dry cell! I will get a video of it running today...

Oh, by the way, I searched around here and discovered that back in 2008 there was a guy named Painless that did the same thing with the lowes swithplate covers. With the exact same setup as me he was able to achieve a pretty good MMW even at higher amps...

Yeah, Painless has been doing this for quite a while now.
As far as your performance is concerned, remember that you're only using 12vdc.
In a car, it'll be getting 13.8vdc. BIG difference!

But... I have no plans to put this in my car- it will allways be running off of 12 volts, thats why I only have 4 N plates because of the lower (12 volts) input to the cell. Right now I am at about 10% NaOh and it is pulling around 20 amps and producing a bit over 1 LPM. I plan to raise it up to 28% solution tommorow by making an electrolyte mix of 1.25 pounds per half gallon (Is that correct?). I am very happy with this cell so far!

[lhazleton]

That's the correct mix for KOH, not NaOH.

Ok, whats the correct pounds/gallon of water of NaOh?

With 5 neutrals on my EBN dry cells I run about 3 tablespoons of NaOH in just under one gallon of water.
