Welcome to the National LCFS Project Website A Low Carbon Fuel Standard (LCFS) is a fuel policy designed to reduce the amount of carbon in transportation fuels. To date, such policies have been implemented in California, the European Union and British Coluia. Several other U.S. states have begun considering similar policies. In 2010, the National […]

18/6/2020· Because carbon, an element, coines easily with other elements to form new materials. The new sf, called compounds, are quite different from pure carbon. An atom is the tiniest possible particle of any element, like carbon or oxygen. A carbon atom
24/7/2020· This allowed scientists to assess the stability of new materials without having to use them in an operational fuel cell over a period of months or years. Using these tests, the scientists showed that loss in activity over the same testing period was around 30 per cent lower in the newly developed graphene-based alyst, compared with commercial alysts.

Carbon (C), nonmetallic chemical element in Group 14 (IVa) of the periodic table.Although widely distributed in nature, carbon is not particularly plentiful—it makes up only about 0.025 percent of Earth’s crust—yet it forms more compounds than all the other elements …
Our CNT material have been used for Supercapacitors, Industrial Gas Detectors, Biosensors, Hydrogen Storage, Fuel Cells, and Composite. XinNano Materials’”CNT-Polymer Composed Conductive Ink” can be easily applied to substrates to produce Transparent Conductive Films (TCF) for Touch Sensors, Flexible Solar Cells, Smart Label, Smart Window etc. appliions.
OUR MISSION To provide innovative, high-quality carbon materials that solve difficult problems, through collaborative partnerships with its customers, who are leaders in thermal, friction, and electrochemical system design. Since AvCarb’s early days in the 1960’s
12/3/2019· Each year, the world consumes more than 92b tonnes of materials – biomass (mostly food), metals, fossil fuels and minerals – and this figure is growing at the rate of 3.2% per year.
22/3/2017· Carbon fibre composites get their strength from long, precisely aligned carbon fibres, fixed within a glue-like polymer that is cured at high temperatures and pressures.
Nanotechnology in Fuel Cells: Discussion of how nanotechnology can improve fuel cells and a listing of companies working in this area. Fuel cells contain meranes that allow hydrogen ions to pass through the cell but do not allow other atoms or ions, such as oxygen, to pass through.
ABSTRACTThis study investigates the emissions of polycyclic aromatic hydrocarbons (PAHs) from a single hydrogen-oxygen proton exchange merane (PEM) fuel cell (FC) and its relation to FC carbon materials. The results show that the magnitude of specific areas or pore volumes followed the order BP2000 > XC-72R > XC-72 > Alfa for carbon blacks and multi-walled carbon nanotube …
29/11/2017· However, carbon materials can be chemically doped by two approaches: substitution of carbon atoms in sp 2 configuration by heteroatoms (substitutional doping) and functionalization on the carbon surface (using a gas, organic molecules, or metals) [46, 47].
meso-Substituted cobalt and Interface Science, Tokyo University of Science (Kagurazaka, Shinjuku-ku, Tokyo 162-8610, Japan) phyrin and various carbon materials. These electroalysts gave rise to electroreduction of O 2 at a remarkably positive potential (E p = 0.44 V versus saturated calomel electrode (SCE) and showed a high selectivity for the four-electron reduction (n=3.9).
This carbon paper meets prescribed properties such as gas diffusion and durability and contributes to improvement of the fuel cell stack performance and space saving. Further, MIRAI’s high pressure hydrogen tank uses the high strength carbon fiber Toray has developed specifically for high pressure hydrogen tanks, which satisfies the safety, strength and light weight requirements of such tanks.

Scientists have created an “artificial leaf” to fight climate change by inexpensively converting harmful carbon dioxide (CO2) into a useful alternative fuel. The new technology, outlined in a paper published today in the journal Nature Energy, was inspired by the way plants use energy from sunlight to turn carbon dioxide into food. “We call it an artificial leaf because it
