What is graphene?
Graphene is the thinnest material known to mainstream scientists. To be more specific, it is about one million times thinner than paper. Because graphene is so thin, some scientists consider it to be two dimensional. At the atomic level, graphene is made of a single layer of carbon atoms. These carbon atoms are bonded together in a repeating pattern that is shaped like a hexagon.
Graphene and fuel cells
Graphene’s ability to conduct electricity beyond ordinary methods is one of the reasons why it is being studied as a material to be used in clean energy and “free energy” applications. According to scientists, graphene allows electrons, which are the particles that make up electricity, to move 200 times faster than silicon.

A TV screen as thin and flexible as paper. A cook's pot that flashes a warning if it detects E. coli. Possible treatments for damaged spinal cords. It's not science fiction -- these are all possible applications of a material known as graphene. This so-called "wonder material" is 100 times stronger than steel but thinner than any known solid. And It's the focus of the latest episode of ChemMatters.
The video explains how graphene's incredible properties come from the unique arrangement of its atoms. Graphene, like diamonds and coal, is made up entirely of carbon. But unlike those materials, graphene's carbon atoms are arranged in two-dimensional sheets, making it incredibly strong and flexible. Since graphene also conducts electricity as well as copper, it could lead to flexible cell phone touchscreens and transparent, inexpensive solar cells. Ongoing advances in manufacturing graphene are bringing these and other devices closer to reality.
