Hydrogen Fuel Cells

What if someone told you about a source of energy that was mobile, used air for fuel, and the only emission was water? Then what if they told you that we have the technology right now and is ready to be introduced into the public. Known as hydrogen fuel cells, this technology exists and is the future of energy. Fuel cells do not use fossil fuels and do not have any harmful emissions. Rather, they run off gasses that we breathe everyday and only emit what all life needs most, water. Hydrogen fuel cells are the future of energy because of their environmentally friendly fuel and emissions.

Hydrogen fuel cells use the energy given off from the formation of hydrogen and oxygen into water. First, hydrogen flows one side of the fuel cell. Here a simple catalyst is used to break apart the nucleus of the atom from the electrons.

As the positive hydrogen ions flow across the membrane, the electrons follow the path of least resistance which is through a circuit. The flow of electrons through the circuit is the usable energy and can be used to power anything electric. When the electrons reach the other side, they meet up with the hydrogen ions and oxygen from the air. Then they all combine and form the fuel cells only emission, water.

Because so many things run on electricity, there are endless applications for fuel cells. Being originally invented for the automobile, fuel cells are perfect for cars. Electricity produces a more lower end power than gasoline which is where cars need power the most. They have been found to be much more efficient source of energy in powering homes and businesses. This allows buildings to be more self-contained by not needing power lines strung to them.
