In the Science Handbook on Hydrogen Hybrid Cars – Water Electrolysis we discussed the structure of the hydrogen cell and how it works, now let's look at the broader scientific aspects. (This will gradually increase to get rid of your old chemicals.)
In the negatively charged cathode (electrode plate) in the water in your hydrogen cell, the impact is still possible. The electrons (e -) from the cathode fall into the hydrogen bonds (ideally charged for the ion observed in the negative electrode in the electrolyte) that form the hydrogen gas, (half equilibrium with the acid):
Code (reduced): 2H + (aq) + 2e – → H2 (g)
In the positively charged anode (electrode plate) in the water of your hydrogen cell, oxidation reaction occurs. This produces oxygen and supplies electrons to the cathode to complete the circuit:
Anode (oxidation): 2H2O (l) → O2 (g) (+) 4H + (aq) (+) 4e−
You can measure these half reactions in your hydrogen cell with a base like the ones listed below. You do not have to adjust all these reaction halves with the base or acid though most prefer the reduction of the reduction or evaporation. For medium reactions, both should be equal to base or acid:
Code (reduced): 2H2O (l) (+) 2e – → H2 (g) (+) 2OH –– (aq)
Anode (oxidation): 4OH –– (aq) → O2 (g) (+) 2H2O (l) + 4e –
You can add any one-and-a-half changes to get the total water difference in hydrogen and oxygen:
Overall reaction: 2H2O (l) → 2H2 (g) (+) O2 (g)
As mentioned before you will get twice the number of hydrogen molecules, as you will do with oxygen molecules. If everything is equal to the pressure and temperature of both glasses, the hydrogen produced will have twice the amount of oxygen. Therefore, the number of electrons in the water will double the number of hydrogen molecules produced and double the number of oxygen molecules
If we look at the thermodynamics of electrolysis in a hydrogen cell car, we see that normal temperatures and pressures do not produce good results. Based on the "Nernst Equation" the standard method for the fuel cell is:
-1.23 V at 25 ° C at pH 7 (H + = 1.0×10-7 M) or -1.23 V at 25 ° C at pH 0 (H + = 1.0 M)
Negative electrical power indicates that the electrical power of the water is more than zero. This is shown using the G = -nFE equation from chemical kinetics, where "n" is equal to moles of electrons and "F" is equal to Faraday constant. This reaction is not possible without additional power, it is always from an external power source.
