(Energy Fanatics) Hydrogen fuel cells that use water to generate electricity are great for producing inexpensive clean energy. With the help of nanomaterials, these fuel cells will become a lot more efficient and affordable in the near future. One nanomaterial that will play a big role in alternative energy is graphene. Graphene is the thinnest material known to mainstream scientists and can be used to create energy out of thin air.
With the right technology, hydrogen fuel cells can be used to power cars, homes, or businesses, saving you money on your electric bill. Imagine driving a car that can go for hundreds of miles on a gallon of water. Hydrogen fuel cells can make this a reality in the near future.
