A lot of people seem to have questions about various electrolytes used in the production of HHO. It would be
a good idea to create some sort of resource to help people understand the various choices out there.
How much electrolyte should I use?
That depends on so many variables it is almost impossible to define. The going answer to this question is
this. Start with figuring out what the maximum temperature your cell design can handle. Subtract about 20%
for safety from that and call it your max cell temperature. It's depend on temperatures and vehicle's power
When you get the lamp of battery check than flushing your generator and reducing electrolyte for refill. It's
happen over tolerance limits of current from Season's temperature and increase usage of electric current in
the vehicle such as the air conditioner in Summer. May vary current of electric than need optimize electrolyte
of HHO generator to meet your vehicles excess electric current. Or you can add PWM for less current
consumption from your vehicle's battery.
Contains god knows what in the way of additives. This will vary from place to place. Does it work? Yes. But
you will have varying results if you need to fill up in a different county. In most places tap water contains
Chlorine as a biological inhibitor. During the electrolysis process this will create chlorine gas along with the
HHO. For anybody with Aluminum parts in your engine this could spell disaster. It has been suggested that
you should let the tap water sit in a open jar for 48 hours with a piece of cheese cloth over the top to keep
out the dust. This will allow the Chlorine to dissipate out of solution, kind of like what some people do when
they first fill a fish tank to protect the fish.
This is by far the most suggested for use as a base. Distilled water by itself doesn't conduct electricity very
well. This means that you will need to add some sort of electrolyte to the mix. If you are trying to be
somewhat scientific about your experimentation then this is what you want. Aqua Reactor strongly
recommend it. The Aquareactor has reached an operating temperature of between 60-80deg C, it
consumes +-75~100ml water for every 1 hour of operation, so filling up with 1.5 liter, should last +- 15 hours
of driving time by calculation.
This has the advantage of being very cost effective as you are already using the AC to keep cool. All you have
to do is collect the condensation for use later. It is distilled water in the general since, but since it isn't in a
controlled environment it may contain impurities. But hey, it doesn't cost any more than the standard use of
Sea water of course contains NaCl or salt. This will be extremely corrosive on your plates. Could also be
real bad if you get any in your engine. There are several thoughts on how this breaks down chemically
during the electrolysis process and will produce poisonous gases. There was someone who talked about
boiling the sea water until the NaCl fell out of solution and then use what is left. It has potential, but be
prepared to replace major components of your cell on a regular basis.
Or H2O2. The stuff you buy off the shelf is only 3% by volume. The rest is just H2O. Hydrogen peroxide
breaks down very easily with light or heat. As such it doesn't do much for you in the long run. It is mildly
acidic, but it turns to water in a very short time once the cell starts to heat up.
Vinegar has a real low boiling point and thus tends to be a poor choice as an electrolyte. What happens is
the cell starts to boil and you loose most of your electrolyte to evaporation. However it works real well as a
cleaning solution for your cell. If you want to get rid of the junk left over from Sodium bicarbonate or finger
prints on the plates… etc… Some even use it to per-condition there cells for a better production rate with
other electrolytes. Distilled White Vinegar may be used as an electrolyte solution on its own, it contains
generally about 75% distilled water. However, We do not recommend it as a catalyst as it leaves behind a
Or NaCl. Creates Chlorine gas during electrolysis. Extremely corrosive. Does it work? Yes, but probably not
the best choice.
Also known as Magnesium Sulfate or MgSO4. Does it work? Yes, but what are you creating in the process?
Any Chemist out there want to speculate? Our high school chemistry suggest that you could end up with
MgO + H2S04. Magnesium Oxide and Sulfuric acid. Again I am not a chemist, so I avoided testing with this.
Also known as Baking Soda or NaHCO3. This is probably the one that most people start out with as they
have it in their kitchen. It does work, but there are better results with NaOH and KOH. It is believed that
sodium bicarbonate will break down to NaOH and CO2 gas in the electrolysis process. Also it creates a
brown colored gunk in the cell and most believe that, over time, will reduce the output of the cell.
Also known as lye, caustic soda or NaOH. Has the advantage of being fairly easy to purchase (usually sold
as drain cleaner). Does not get used up in the electrolysis process such that all you have to add is water
periodically. Great results. Can burn the skin if you come in contact with it.
Also known as potash or KOH. Considered by most to be the best option. Can be found in specialty shops
that make soap. It conducts electricity better than NaOH so less is needed in solution. Like NaOH it can
burn the skin if you come in contact with it. Aqua Reactor strongly recommend it.
This is a bad catalyst to use, it will facilitate a reaction but will produce chlorine gas as a by-product. Salt will
also facilitate damage to your electrodes over time.
As with Salt, Baking Soda will also create chlorine gas and damage your electrodes.
