1 Kg Hydrogen Electricity Production
On the power generation of one kilogram of hydrogen
Now I want to study how much electricity can be produced by one kilogram of hydrogen. Hydrogen is a clean energy source, and it has great potential in the field of power generation.
Hydrogen power generation depends on the technology of fuel cells. Fuel cells can chemically react with hydrogen and oxygen to generate electricity and water. The reason for the reaction is that hydrogen atoms lose electrons and form hydrogen ions. Electrons go through an external circuit to generate electricity; hydrogen ions combine with oxygen to generate water.
The theory says that if one kilogram of hydrogen reacts completely, the electricity produced is quite considerable. According to stoichiometry, the molar mass of hydrogen is about one gram per mole, and one kilogram of hydrogen is one thousand moles. In an ideal fuel cell reaction, two moles of electrons are transferred per mole of hydrogen. According to Faraday's law, one mole of electrons carries about 96,485 coulombs. From this calculation, the total electricity transferred by the reaction of one kilogram of hydrogen is one thousand moles multiplied by two multiplied by 96,485 coulombs, and the resulting electricity is very large.
However, due to the actual situation, the efficiency of the fuel cell cannot reach 100%, and there are losses such as heat dissipation and internal resistance, the actual electricity produced by one kilogram of hydrogen is lower than the theoretical value. Although this is the case, the high energy density of hydrogen still allows it to generate enough electricity for one kilogram to power many electrical appliances for a long time.
Or in small portable power generation devices, the electricity produced by one kilogram of hydrogen can make low-power electronic devices operate for several days; if used in larger distributed power generation systems, it can power several households for more than one hour.
It is necessary to say that the power generation of one kilogram of hydrogen, although it is different from the theory due to practical factors, has unlimited potential in the way of energy. When technology improves, it will be able to contribute more to the production of electricity.
