Not sure about the wet cell, but you should consider a dry cell set-up as it will be more efficient, easier to manage and produce more HHO.
The hotter the water gets the more the amp draw in a dry cell, this is where the PWM comes in, it will stop the thermal runaway.
Another solution to the thermal runaway problem, and i can confirm this ACTUALLY works, is to restrict the water flow from the reservoir going directly into the dry cell, restricting the flow will not only reduce amp draw, and stop the water reaching 70 degrees c but also, reduce the amps and voltage needed to produce the same amount of HHO.
Ive tried it, it really works!
