Hi,
I am tooling up to explore some HHO production ideas and am wandering about the relative merits of acid verses base electrolyte?
I have hard tap water, so I will be making 3 meg Ohm/cm or better water, therefor will need to add ions of one sort or another.
My initial thoughts are nitric acid (hazards acknowledged), my cell is glass with stainless steel plates nylon fixings, ABS, polystyrene, and silicone rubber fairly common I would think.
I am keen to avoid the scum and gunk that I have come across in my preliminary work.
Any pointers ideas welcome.

I'm not sure that stainless steel would last long in nitric acid, especially one thats been excited by energy, carbon is one way to go, I'v also heard that titanium might work, whatever you use for the electrodes really needs to be resistant to corrosion.
?I am only looking to add a few percent acid to get some conduction going. 316 S/S is usually very corrosion resistant! But add a current and I guess any thing goes!!

Perhaps adding sodium hydroxide might be enough to increase conduction.
