Water and electrolyte setup
Principles of the water electrolysis
Electrolysis of water is the decomposition of water molecule (H2O) into oxygen (O2) and hydrogen (H2) gases
due to an electric current passing in the water.
An electrical power source is connected to two electrodes, or two plates (typically made from some inert
metal such as stainless steel) which are placed in the water. In a properly designed cell, hydrogen will appear
at the cathode (the negatively charged electrode, where electrons enter the water), and oxygen will appear at
the anode (the positively charged electrode). The amount of hydrogen generated is twice the number of
moles of oxygen, and both are proportional to the total electrical charge.
Electrolysis of pure water requires excess energy in the form of potential to overcome various activation
barriers. Without the excess energy the electrolysis of pure water occurs very slowly or not at all. This is in
part due to the limited self- ionization of water. The efficacy of electrolysis is increased through the addition
of an electrolyte (such as a salt, an acid or a base).
Electrolyte concentration
The electrolyte should be added to the water the first time that
you use the system, and also when refilling, but in lower
quantities. Amperage should be measured to ensure the right
operative conditions according to the table below.
The electrolyte concentration to use in the HHO system depends
on the type of electrolyte and the purity of the product. The best
electrolytes are KOH (Potassium hydroxide) and NaOH (caustic
soda).
The more electrolyte you add to the water, the more amperage you will have in the system and also more
HHO gas will be produced. But, It is false to assume that a higher HHO gas production will mean a higher
fuel savings. There is an optimum point for all internal combustions engines. In diesel cars the system should
provide around 0,25 liter/min of HHO gas per each 1000 cm
3
of engine displacement. You will be meeting this
standard running your generator with:
Water is getting a brown color
after only a few hours
working?
You have too much electrolyte
in the system that is "eating"
the generator plates too fast.
Remove the water immediately
and start all over again.
