Everybody was a newbie once
This cell has only the shape in common with the Joe-cell, it's a single cell, in a round form, zo you have seen that correctly.
It also means that the voltage schould be low, between ±1.3V and ±2.0V
So this cell needs to be with a bunch of partners, to serie up
A Joe-cell has a large myth around it, no proof anywhere, but it's just a serie-cell in my opinion, with large leaks I might ad.
Ask away, that's why fora exist, but please use the search function first

Bob has a good point about the "hot spot", but I believe that, where the hot spot is, the gas will give a higher resistance, so the current will flow where there is less resistance, being the rest of the surface area.
About heating up; I'm not worried about that (or I'm not getting this right yet)
This cell schould be able to take 100A, when I'm calculating at 0.5A per inch².
Also, is it not so, that a voltage below 1.5V per cell, will keep the cell cool?
That's what eventualy would be the end product: ~1.3V per cell.

I've knocked up this cut through diagram which should illustrate it better. Appologies for its crudeness.
...just need to find a source of stainless steel pipe now.

The inner side of the outer tube is one surface (lets call it negative)
The outer AND inner side of the seccond largest tube is the other surface (positive)
The innner AND outer surface of the third tube is again negative.
The small tube only uses the outside. again positive.
Thats why the total surface of the negative is the same (allmost anyway) as the surface of the positive.
In other words, tube 1 and 3 are negative, tube 2 and 4 are positive.
Please recalculate, then you will see what I mean.
It's a bit confusing I presume, but the small tube and the second largest tube are connected via the perforated round plate on top of them.
The other two tubes are connected via the bottom plate.
If I'm not clear enough, I'll be happy to draw a small scetch, let me know.
