Although graphene is known for its beautiful symmetry, some graphenes with flaws and structural imperfections are not inferior. On the contrary, they have more interesting prospects, especially with the potential to produce better and cheaper fuel cells.
Several scientists from Northwestern University and several institutions worked together to obtain this so-called "defective" graphene material by knocking out four or more carbon atoms in the original structure and playing with it happily. They used this material as a hydrogen fuel cell membrane, and the "defective" exhibited greatly improved performance compared to the normal structure of the graphene material. Within a few seconds, a large number of protons easily pass through the "defects" of only one carbon atom thickness, thereby realizing efficient power generation.
The biggest problem with existing standard fuel cell membranes is their poor selectivity, allowing large amounts of impurities to pass through together. In contrast, "defective" graphene not only transfers protons much faster, but also is more selective to the particles that pass through. This can provide relatively simple and highly efficient fuel cells for electric vehicles and even wind and solar power plants. Researchers believe that this technology can also be used to improve the performance of ordinary batteries.
Although for a variety of reasons at present, graphene is still only a hope star on posters, no one uses it, but there is every reason to believe that at some point in the future, people buy green cars that are made of graphene. Battery to provide power.
