Ok you dry cell guys, I currently am working on a dry cell -NNNN+NNNN-, I have measured output because I broke the cap for the resevoir and havent had time to fix.

Question is, what configs are you guys using? And where, how many, and size of holes in the plates? I guess I just dont know the internal looks of the dry cell. My cell currently runs in spurts the water doesnt flow consistently.

Raise the reservoir.

Also, make sure the tubing runs are straight with no dips and dives.

I'm running +NNNNN- times 4 at 2.33 LPM with Lowes switch plate covers. I use the standard mounting holes they come with for electrolyte flow.

what kind of amps are you drawing?

Painless,

Are the plates you are using the 1 gang ss plates?

Painless,

They are the 304SS plates made by cooper. They are the only ones Lowes have without premade holes for switches.

If by one gang you mean they cover a single switch, then yes.

Can anyone explain +nnn-nnn etc. I'm in the dark.

And, does anyone know where I can see a drawing of a finished closed cell
device?

Thanks,

Charlie

+nnnnn-

Is the simple way to describe your plate configuration. The plus and minus symbols each represent a plate that has a power connector attached. The "nnnnn" are plates that are not connected to any power lead. Some refer to these as neutral plates, however they is a bit if a misnomer. The unconnected plates still conduct electricity via the electrolyte. By adding the "n" plates you drop the overall voltage for each plate gap. This has the effect of reducing heat production. You want something between 2.0 - 2.4 volts DC for each plate gap for the best production. Anything more will just create heat.

So in a car, a +nnnnn- configuration works out to something like:

13.8 VDC divided by 6 plate gaps = 2.3 VDC per gap.


When you see them listed as:

+nnnnn-nnnnn+nnnnn-

This just means that they have combined multiple cell stacks in series. It still has the same voltage drop across each plate gap. This allows you to increase your plate surface area.


Assuming that by "Closed Cell" you mean "Dry Cell" check out:

Excellent explanation Q-Hack, I have a hard time understanding this also, but its slowly sinking in.

The 13.8 amps mentioned here, its measured at the power point, not the alternator, correct?

I've seen that +nnnnn-nnnnn+nnnnn- configureation mentioned a few times, this appears to be the better set up mentioned by the more experienced testers here.

The 13.8 should be Volts DC not amps. Most cars charging systems operate somewhere between 13.5 - 14.5 volts. You can measure this at the alternator or at the battery itself. It doesn't make that much of a difference.

Hey fellow HHOers!

I was wondering what you are using to attach the Lowes Home Improvement plates to each other, and what spacing you are using. I have tried to assemble them using plastic toilet bowl seat bolts and plastic washers for about 1/8" spacing but the curvature of the plate always produces issues and eventually I lose connection - probably due to either my copper wiring being in the solution, or rust/erosion of the wire connectors... Anybody have any thoughts on the connections, while I'm at it?

Oh, and who all is using Mason Jars - or are you guys using PVC or building your own plexiglas boxes?

Thanks!

Hi Joe,

Contact between plates due to the angled edges is one issue with the dry cells constructed from Lowes plates, I was using an 0.040" gap with PVC shower pan liner and not placing bolts through the plates themselves, I would sandwich them between two plastic end plates and use the bolt pressure to create a seal.

For connections, I used a dremel to cut tabs in the top of the angles, you can then use spade connectors for the poles.

DO NOT use mason or any other kind of glass for reservoirs, bubblers etc unless you are going to surround it with something that can resist an HHO explosion. An HHO explosion inside a glass jar may as well be a fragmentation grenade going off. I use plastics, like PVC.

Russ.

Sounds like you are building an open bath setup. Am I correct?
