HHO Generator Overheat

Why is there so much heat produced, such that it melts the lid and also creates steam?

Conditions: HHO Generator glass container with a plastic lid.
- stainless bolts through the top of the lid with rubber gromets
- 2 stainless wall plates for the electrolisis process (gap approximately 2mm) gap provided by nylon washers, held together by nylon bolts and nut
- currently using stainless wire to connect from the bolts to the plates
- current provided by either a battery charger or a 12v car battery (basically using jumper cables)
- Distilled water with baking soda (I've used anywhere from 1/4 teaspoon to as much as 5 teaspoons with the same results)

Results: Good HHO generation, but...
- plastic lid melts within 5 minutes
- starts out pulling about 10 amps and jumps to about 80 amps! Yeah... don't touch that lead!
- water gets hot and starts to produce some steam

Diagnosis?
- I can't find any shorts
- I need your help!

It looks so easy on all of the different websites, but I'm obviously doing something very basic, wrong. Can you help?

1. Try running it without any baking soda.
2. Try running it at a reduced voltage.
3. If it still gets hot and makes steam, consider building a steam engine for auxiliary power. :lol:

Heat equals wasted energy.

Electrolysis is caused by the current flowing through the water; it is independent of voltage.
12v and 20a makes the same amount of gas as 1.2v and 20a.

The minimum theoretical voltage to produce hydrogen is ~1.2v.

If your electrolyzer is overheating, it means you're feeding it too much voltage. Maybe run a few of the "cells" that you've made in "series." This is how you make a "series cell" which is much more efficient and therefore produces much less heat.

Pinhead,

I'll give that a try. Thanks for the input. Sounds right! I'll let you know how it works on Wednesday.

Thanks,

I have a dual fuel cell with 304 stainless steel . With a reservoir for the liquid and am using caustic (LYE) for the chemical. You can check it out at "http://www.preignitioncc.com/flash920G" I am getting 60 ltrs per minute drawing 12 to 15 amps for 1 cell and 24 to 30 amps for 2 cells. We use single cell for 4 cyl. and both cells for 6 & 8 cyls.

You're getting 60 ltrs per minute ???????? Don't think so, never seen HHO production numbers that high ever......

Even 6lpm is high. With two cells, are you sure you don't mean 0.6 L/m??

He probably meant to say 60 L/hour or 1 L/min.

To answer the thread topic, I agree with Pinhead. Primary cause of the overheating is per cell voltage too high. Best way to reduce the per cell voltage is cells in series. Divide total supply voltage by the number of cells to get your per cell voltage. For a typical car when running you should be able to run 5-6 cells in series without any trouble. This will get your per cell voltage down to 2-2.5 volts. My generator with 6 cells runs at 8-11 amps (depending on temperature) and does not exceed ambient temperature by more than 4-5 degrees F.

Thanks for the help! Pinhead, you hit the pin right on the head! Multiple cells was the ticket. I basically used the Smack Booster plan and its working like a champ.

Spock,

At the moment I'm only getting about 250ml per minute. I'm having trouble keeping the gaps close enough on all of the plates (1 nylon washer). The plates tend to broaden out at the ends. I may go for a different tactic and drill 4 holes at the corners to tighter down the outside portions of the plate. Believe it or not, the wall plates have been eating up a titanium tipped drill bit. Not sure what that's about. Maybe a bad batch of drill bits.

As I'm writing this I"m thinking that maybe the nuts are too tight on each plate. I'll try loosening them and let you know.

That is not surprising. Stainless steel is tough stuff it does not like it when people try to make holes in it.
Use a slow drill speed with moderate pressure and perhaps a little cutting oil.
