Hi guys. I'm new here too. I just built a Tero Cell and I'm hoping someone here might have some insight to the cause of my problems. I have built a couple of different designs before this and can't seem to get my amperage up high enough except for my first one (I called it the "heat generator"). This lastest try is two Tero's in parallel (but within one housing) and my total current has not gotten over 4 amps. I am using a 28% KOH solution with distilled H2O, and my plate area is around 26in2 per side (below the electrolyte). I am only getting about .3 lpm. From all of the forums I have seen, I should be getting much more than this from a single tero, much less a double. Anybody have any ideas that might help me get the amperage up?
Thanks
Welcome to the forum sritter

lets see if we can track down your problem.
First off what size plates did you use and how many? If you followed the tero plans and used 8 plates this would be an amp and output flaw.The Tero plans call for 8 plates which have been found not to be efficient.The spacing between the plates should be at least 1/8" or less if possible.
When you say you ran both in parallel what configuration did you use?By this I mean are the plates configured something like this -nnnnnn+nnnnnn- using 15 plates or -nnnnn+nnnnn- using 13 plates?
Also I've found that using more than 30 % koh by weight in a tero cell does not further amp draw or output.30 % seems to be the limit of usefulness of koh,at least from the % testing that I've done with my tero cell I saw no change from using 30 % as opposed to up to 45 %.I think your problem may be in either construction or plate configuration or maybe both.
Two other questions regarding you e-lyte mix,did you use only distilled water when mixing your e-lyte,and the actual amount of koh was it about 1 lb.koh per 1/2 gallon of distilled water(which is 28 % by weight) or other?
