Another question: how did you connect the plates?
I have 13 plates here, that'll make 12 chambers. At ~1.5V / chamber i would put ~18 Volts on the outer plates and leave the other ones in between unconnected. Will that work?
You only connect 2 endplates. Rest are neutrals.
My two endplates have special "ears" on which i can mount a connector on.
I have used also weldwire welded on plates, which is working fine as well.
If you work with a gapspace of 1mm, and you use KOH or NAOH, then a voltage between 1.5V and 2.2V should be enough to get the best performance/efficiency.
We can meet on MSN or skype if you like. Then we can talk about as much as you want.
