The best HHO Electrolyte (catalyst) for HHO Gas Generator?

Use an electrolyte that suits the best to you  HHO Gas generator design. The distance between the electrode plates does really matter.

A -  For electrodes with little distance between the plates you could use: tap water or distilled- rain- or demi water with a very little of any of the catalysts mentioned below.

B - For electrodes with more space between the plates tap water won't work.  So use distilled- rain- or demi water with a little of the catalysts mentioned below. 

C - For electrodes with a lot of space between the plates tap water  won't work.  Use distilled- rain- or demi water with a one of the catalysts mentioned below. 

 


1 - Tap Water - H2O (containing minerals, salts etc.)

Advantages:

  • Available everywhere
  • Cheap
  • Safe

Disadvantages:

  • Water might  turn brown with smudge on the electrodes 
  • Water that contains chlorine should not be used

  

   

2 - White Vinegar - acetic acid -  H3C-COOH

Advantages:

  • Stainless electrodes stay clean
  • Available everywhere
  • Cheap
  • Safe

Disadvantages:

  • Smells 

 

Available at your local grocery store.

A good mix for medium distance electrodes: 100% vinegar with (only if necessary) some baking soda. (If do so be carefull, because the reaction will produce co2 and some other  gasses!)


     

    

2 - Baking Soda ( Natriumbicarbonate )  NaHCO3

Advantages:

  • Available everywhere
  • Cheap

Disadvantages:

  • Electrodes and water might turn brown
  • Produces Co2 (30%)  and Co (4%).
  • For this reason not recommended

Pure Baking Soda might leave a brown tinted residu.

 


       

3 - Sodium Hydroxide also called Lye = NaOH

Advantages:

  • Electrodes stay clean
  • Cheap
  • 95 - 100% pure HHO (oxygen hydrogen) Gas production with right generator design 
  • Safe
  • Available in the Grocery store
  • recommended

Disadvantages:

  • Limited dangerous to work with

Pure sodium hydroxide is a white solid; available in pellets, flakes, granules and as a 50% saturated solution. It is deliquescent and readily absorbs carbon dioxide from the air, so it should be stored in an airtight container. It is very soluble in water with liberation of heat. Use with distilled water.


 

4 - KOH

Also called pottassium hydroxide.

Advantages:

  • Electrodes stay clean
  • 95 - 100% pure HHO gas production along with the right generator design 
  • strong and pure electrolyte

Disadvantages:

  • Not available everywhere
  • dangerous to work with 

Recommended as very good electrolyte  (recommended by Honda in 2001)


 

5 - K2CO3    

Pottassium Carbonate.

Advantages:

  • Maximum HHO gas production
  • Very pure HHO gas production along with the right generator design 
  • Efficient
  • Safe to work with 

Disadvantages:

  • Not available everywhere
  • It is possible (sometimes necessary) to mix it with a little Naoh to draw more amps.

Winter Electrolyte:

Developed by mr. M. Moldoveanu

Water+Ethyl Glycol+KOH will provide the benefit the technical of low freezing point but high boiling point at the same time. 


 General information to get the best results:

For the flat-plate-design electrodes you might want to consider pulse power to get more efficiency using less amps making better gas.  VERY good results are possible with a Stanley Meyer like PWM.

For most cars between 4 - 20 amps should give good results. Medium Diesel engines need less amps (2 -12) Prevent to add too much watervapour into Diesel engines. Too much watervapour will delay the ignition of the fuel mixture which might cause using more fuel.   

Do not try to get too much HHO gas volume out of your generator by using a lot of amps etc. It will certainly become overheated and your electrodes could be damaged. Or you will generate steam. It is better to a larger number of  (small) generators to get the gas volume you need. Or use a HHO generator with a pump system. Advantages: The generators will stay cool / warm, uses less power, is safer and will last longer(!)


Your optimum draw should be several amps less when cold so keep adding little by little. until you get to your optimum amp draw. (sometimes it will double)
