As the diagram above shows, water consists of 2 atoms the blue being oxygen and the green hydrogen. When a charge is applied under the right conditions, the oxygen (being negatively charged) will flow to the positive plate and the hydrogen (being positively charged) will flow to the negative plate and the two hydrogen atoms and single oxygen atom that make up water (H2O) are pulled apart. This process is known as Electrolysis.
In a normal engine, the fuel is injected into the combustion chamber with air where they mix and in a very short period are ignited so that the combination burns, expands and forces the piston down so that it turns the crankshaft which in turn drives the car forward via the clutch, gears and wheels.
If you are travelling at a 100Kmh and the engine is running at 3000 RPM, a piston is inhaling the air/fuel mix and firing every 0.02 of a second.
As you can see diesel has 16 parts carbon to 34 parts hydrogen, and petrol has 8 parts carbon to 18 parts hydrogen. From this it can be determined that an engine uses mostly hydrogen to run as it makes up the bigger part of the fuel and hydrogen burns at a much faster rate than carbon.
Carbon is a solid and hydrogen is a gas, so fuel is sprayed into the combustion chamber under high pressure to get it as close to an atomised (gas) state as possible - however, true atomization is never reached.
In conventional fuels there is only enough hydrogen to burn the outer parts of the carbon atom and the remainder is exhausted as emissions into the environment. It is estimated that most engines manage to achieve less than a 60% burn of the carbon.
However, a Hydro-Fuel Cell producing 1 litre of hydrogen per minute is producing 2.688x1022 of hydrogen atoms per minute. This adds a surge of hydrogen atoms to the combustion chamber, assisting the carbon atoms to burn completely as free hydrogen atoms surround the carbon atoms. Our tests have shown that when the Hydro-Fuel Cell is switched on, the carbon is burnt more efficiently and that up to 99% of the carbon is burnt.
To illustrate the principle, consider the carbon atom to be a charcoal briquette. If you place two small pieces of firelighter and put them under the charcoal, it would take a while for that charcoal to burn. However, if you completely covered the piece of charcoal with firelighters it will burn so much quicker and more completely in the same time period.
