A fuel cell vehicle (FCV) or fuel cell electric vehicle (FCEV) is an electric vehicle that uses a fuel cell, sometimes in combination with a small battery or supercapacitor, to power its onboard electric motor. Fuel cells in vehicles generate electricity generally using oxygen from the air and compressed hydrogen.
Recent advancements in battery technology and charging infrastructure have addressed many of the earlier barriers to EV adoption, making electric vehicles a more viable option for a wider range of consumers. [23] The carbon footprint and other emissions of electric vehicles vary depending on the fuel and technology used for electricity generation.
1 T to 2.4 T – coil gap of a typical loudspeaker magnet; 1.5 T to 3 T – strength of medical magnetic resonance imaging systems in practice, experimentally up to 17 T [10] 4 T – strength of the superconducting magnet built around the CMS detector at CERN [11] 5.16 T – the strength of a specially designed room temperature Halbach array [12]
Monroney label showing the EPA's fuel economy equivalent ratings for the 2011 Chevrolet Volt. The rating for all-electric mode (left) is expressed in miles per gallon gasoline equivalent (mpg). Miles per gallon gasoline equivalent (MPGe or MPG ge) is a measure of the average distance traveled per unit of energy consumed.
Battery electric cars are becoming more and more attractive with the higher oil prices and the advancement of new battery technology (lithium-ion) that have higher power and energy density (i.e., greater possible acceleration and more range with fewer batteries). [12] Compared to older battery types such as lead-acid batteries.
This type is actually electric vehicle that is powered by electric energy generated using onboard fuel cell. Fuel cell uses hydrogen stored in hydrogen tanks and oxygen from the air to create water and electricity. Water is discarded but electricity is used for propulsion. Similarly to Hybrid Electric Vehicle, there is a small traction battery.
