Calculation of maximum Hydrogen output. Question: -How to calculate the amount of Hydrogen (HHO) that a generator can produce?

Answer: Generation of Hydrogen is based on electrolysis, which is governed by the laws of physics. This process was studied almost 200 years ago by Michael Faraday, who subsequently published “Faraday’s Laws of Electrolysis”.

The laws state that an electrolysis cell, operating at a certain current (amps) will produce a known amount of HHO.

The two main considerations are the number of electrode plates and the actual ‘active’ surface area. The active area is the surface area of the plates minus the area of the gaskets.

For example, if a Gen 10 hfs generator has cell figuration plate area of 2000 square cm ( Gen 15, Gen 20 and Gen 30 systems have increased plate area configuration)

Michael Faraday also demonstrated that electrolysis cells can support up to 0.084 amps per square cm without overheating. This is the standard used to design a HHO generator.

Therefore, the 2000 square cm cell can support up to 168 amps of current which is far in excess of a cars alternator / battery capacity.

We recommend no more than 20 amp output

Calculation of maximum Hydrogen output. The number of electrolysis cells is also very important. Too few and the generator will have poor HHO production and overheat. Too many Cells and the generator may not work at all.

For 12 volt vehicles, the ideal number of electrolysis cells within the generator is 6 , so as to use up all of the available voltage

As a mathematical simplification of Faraday’s laws, a HFS Generator will produce 90 ml/minute of HHO per 1 amp of current

So, the generator in our example will have a maximum output of 1.8 LPM (90 ml x 20 amps)
