I was wonderinf if that matters and or how to cool it down, also I'm using tap.water and a teensy bit of lye.
If you only have room for 13 washers, then configure it as: -nnnnn+nnnnn-. If you supplied 12V to this configuration, it would give you essentially 6 cells in each of 2 banks running at 2V each. In your current config, you have 3 cells in each of 4 banks running at 4V each. You only need about 1.75V to generate HHO from water, anything beyond that does nothing but generate more heat.
That said, I would not consider that setup to be viable for anything other than bench testing / exploring HHO. That sort of setup would be quite less than ideal for installation on a vehicle. HHO gas is flammable, and generating that in a glass jar is a grenade waiting to happen. At home testing wet cells, I used plastic, and designed a fail point somehwere in the cell that would release readily in the event of accidental ignition of the gases within the cell.
I hope that helped you some, I am by no means a guru, and someone may even offer a correction to the info I provided, but I hope to have steered you closer to a safer, more efficient cell.
WTB dry cell for my 1.8L Toyota Corolla. Looking for a 7 plate setup +nnnnn-. I only need the cell itself. PST with pictures of any available kits.
