Help with plate design

[VanHalen]

So I may be recieving some precut stainless steel or more than likely titanium plates, all depending on if the supplier comes through. They will be about 3" by 5", and I had a couple questions.
A- What effect does spacing have on the plates and output.
B- If I have 6-8 plates, would there be any need for nuetral plates and what should I run them in?(ex ---NN+++)
C- Would plummers PVC pipe work for a container, and if not what is reccomended?
D- Should I run the gas through a seperate bubbler, and what the purpose of one is?

You should use 7 plate configured like this -NNNNN+

Space them 1.5mm apart, any closer and you will likely raise your amperage with no more production. If they are farther apart you will get less production.

You can use ABS or PVC pipe.

Wrap the cells with shrink wrap or a suitable tape. This will prevent stray current.

You need a bubbler to scrub the hho gas and also to prevent a flame from destroying your cell.

Refer to this link for a cell similar to the one I use.
