There are already several alternative sources of energy. One of these alternative sources was originally intended for space programs but now, some studies are already considering it for car use. Hydrogen fuel cells are indeed gaining much attention in todays times when there is a great need for another energy source.
The hydrogen fuel cells are just like traditional batteries. A chemical reaction produces electricity and electrical charge. However, there is still a difference. You see, with batteries, power is produced if the cell is continuously supplied with hydrogen. To understand how the fuel cells work, read on.
The cells size and hydrogen flow determines the electricity produced. When a chemical reaction occurs between air and hydrogen, three things are produced namely heat, water, and electricity. Fuel cells lower heat output as compared to other sources of energy like the fossil fuels. But still, there are advantages in using hydrogen fuel cells.
One obvious advantage is that fuel cells are clean since the byproducts are heat and water. These byproducts cant harm the environment. Fuel cells have efficiency rates ranging from 45-53% as compared...
