Possible new layout for H2 dry cell
Even though I am gong down the structural route put forth by Finallyme some time ago, clearly the dry cell is the most efficient. I chose to start with the Finally's structure because I just couldn't see how to seperate the gasses and still keep the dry cell small. Space is a big problem in my van. As I have run down my path, it is quite possible that the Finallyme design may not put out enough H2 but I am still hopeful. As a backup I have been mulling over the dry cell problem for a month and I think I might have a break threw. So I thought I'd ask the H2 dry cell experts (all 3 of you. Its lonely out here in H2 territory) what you think.

Firstly, I apologize for the drawing. I only have paintbrush but I think you should get the idea. The design in the drawing allows you to have 3 cells with just 2 end caps. You could extend the principle to have more cells but that would increase the size of the genorator. At the 3 cell size, you could make 2 gens and series wire them to get that magical 6 cell operation. For me it is easier to place two smaller gens under the hood than one big one. Of course, I have never made a dry cell so I don't know how hard it is to make different gasket shapes. At any rate, let me know what you think. Thanks.

That's a similar design to what I came up with a few weeks back. I suspect you'll need thicker gaskets to keep from having a restriction or make them slots instead.

Dump the Paint. Try Paint.net, it's a free download.

RE: Possible new layout for H2 dry cell
Well, then what you are saying is that the structure is viable. Of course I don't know how tough it is to do the gaskets. We'll have to see what the master builder Gary has to say about it. He seems to be able to whip these things together in blinding speed. It takes me forever to do anything! I don't know how he does it. And Hydro cranks these things out too. It's pretty amazing actually.

I think its very duable, And I would recommend using a O-Ring material that can be purchased in bulk,(some places sell it by the yard) and in any diameter. All you have to do is lay it out in the pattern you want, lock it down with dots of supper glue. The ends you cut on an angle and use the special glue made fore material and bond the ends togetherfor a good seal. Doug.

RE: Possible new layout for H2 dry cell
I'm not understanding the gasket setup yet. It looks like you've assigned two gaskets to one spot in the center, on both sides of the center plate, so I'm lost.
Loctite #404 bonds the ends of roll o-ring together and regular *cheap* superglue bonds them in place to the plates to hold until compression. I've just straight cut them and haven't had a leak yet. I forgot they recommend an angle.
Assuming some size to the plates, expect about 330ml/min. of H2 max at 18-20 amps. (using 6 plates for 3 cells.
...and thanx for the roses...

If you're going to use o rings, you'll have to add small ones around the other gas (one that isn't exiting now) so it gets passed thru to the next cell.

It's not the greatest picture. The thick lines are the plates. There are four plates. The thin lines are the H2/O2 filter screens. The G:B template is used on the right side of plate #2 and on the left side of plate #3. In the picture I am assuming flat gaskets that go all the way to the edge of the plate. Lock tight 404 and superglue. Got it. I have also copied your post into my SS database. I keep loosing good info on the forum and can't retrace it so I started a database.

Hey, you have done a ton of good work and unselfishly shared and have helped a lot folks by doing so. Your welcome.

Colchiro. You are right. If you use round gaskets you would have to do full circles around the holes for carrying the gas out passed all the other plates to the appropriate exit tube. Of course, you would not have to use the circle around the hole of the gas chamber you are evacuating. The circles are just for bypassing. But I think a flat gasket might be easier to work with. You won't have to be so exact in lining up round gaskets to meet each other perfectly so that there is a seal. I think. I haven't worked with any of these materials so I don't know.

Thanks Milo for your input. It looks as if we can slim down a dry H2 system.

RE: Possible new layout for H2 dry cell
That's what I was thinking too, if the gaskets didn't match each other from plate to plate, they might leak. I suspect a little variation (within 1/8 to 1/4 inch) would be ok, but you I would think it needs to be close.
