graphite manufacturers to produce pure enough15/7/2015
ation from the air filter, helps to obtain power from the hydrogen fuel cells.Their paper published in the journal nature.Graphene can be used graphite machining as a proton filter membrane. Ten years ago, people china graphite for the first time off the world, the http://ipeace.us/profiles/blogs/future-will-graphite-machining-usher strongest material graphene, the thinnest experiment in hundreds of USES for it, including batteries, night-vision goggles, medical scanners, light detector, and even a condom.Until today, the material is still constantly bring us surprise.Nature and in the latest issue of the journal science, the British and American scientists new papers published respectively, an article points out that although graphene impervious, can let the proton through, it could be used in fuel cell as a thin membrane;Another said graphene under http://michaelkors666.metroblog.com/fat_graphite_manufacturers_a!commitment_to the bullet impact performance is better than steel and body armour graphite manufacturers material. Fuel cells can be dissolved hydrogen into protons and electrons, thereby to convert chemical energy stored in the hydrogen into electricity: electronic along the external wire forming current, proton flow through the battery internal http://chinagraphitemanufacturers.iconosites.com/ membrane.The battery in the film, such as commercial, thin film (Nafion) about 10 microns thick, still cannot completely prevent hydrogen leakage, also let protons can't flow smoothly, detract from the power.If there is a kind of super thin membrane, can solve these two problems.Geim said, this is the advantage of graphene. But fuel cells experts point out that the study also demonstrated in theory stage, can you apply to be cautious.In addition to consider how to produce pure enough, big graphene layers, factors such as cost and service life. Geim group with graphene membrane filter the pure hydrogen from water.Geim said the technology could also separation of hydrogen from the air, "it also belongs to the speculation, but before the published papers, it still in the stage of science fiction."Last year, researchers have demonstrated a stack of graphene oxide film can produce tiny channels, from carbon dioxide or nitrogen hydrogen.
