Hydrogen is the most common element in the Universe and is a perfect ‘green fuel’. On Earth, however, it does not exist in large quantities as a gas. Because of this, hydrogen must be extracted from other resources such as fossil fuels, biomass, or water. Hydrogen is considered a clean, inexhaustible energy source.
A fuel cell is a system that uses hydrogen as its fuel source through an electrochemical process, rather than through combustion. Click here to learn more about how hydrogen works with fuel cell technology.
