Chlorine smell? Something to do with salt being made of chlorine and sodium?
No I currently have no pictures on my computer, but making it was simple.
17 1mm stainless plates (maybe 10cmx5cm) were clamped together and I used a cutoff wheel to notch one corner (the right width for female spade terminals to push on to) of each plate.
Turn every other plate around (helps to identify them for wiring), and space them apart with rubber washers (I used the ones found on roofing screws). Then clamp the whole lot together. I used nylon zip ties, but apparently you can get plastic bolts that would be better (as then the rubber washers would have something to positively locate them).
Make the power feed wires by joining 10 wires together and crimp 9 spade terminals onto the bundle (other wire goes outside the unit). Repeat, but with 9 wires and 8 terminals. Join the 9-terminal plug to the outer plates and every other plate. Join the 8 terminal plug to the others. You want the plates to alternate positive to negative, so both sides of all the middle plates are active.
Now get a container with a sealable, removable lid (I used PVC piping and fittings). Drill three holes in the lid, two of them are for the power wires, hydrogen and oxygen come out the other. Use silicone (or similar) to seal any holes and fittings, and make sure that your lid has a good seal (another bonus with PVC, screw on lids have o-rings).
Fill the container with a distilled water and electrolyte mixture (I used something you know as dran-o, and it doesn't leave deposits on true stainless plates, but my electrical terminals show *bad* signs of corrosion). Now if you left long enough wires you can attach the cell to power with the lid off and see the hydrogen/steam mixure coming off (don't fool yourself, at 12v across this cell, a lot of energy goes to heating water and not making hydrogen).
To be safe you want to feed this mixture through a bubbler to a) stop explosions from reaching the cell and b) stop electrolyte from entering whatever device you have.
As with all electrolysis, this generator makes hydrogen and oxygen in a perfect stochiometric ratio (chemically correct ratio for complete combustion). Hydrogen and oxygen is one of the most powerful explosives (by mass) you can easily make, so for God's sake, be careful. At best being near an exploding hydrogen generator will cover you in shrapnel and an acid-like solution.
*edit: The multi-cell design uses 6 similar (but smaller) multiple plate assemblies in series in the 6 separate cells of an old battery with a fabricated lid (the old lid was damaged in dissassemby, and unsuitable anyway)
