A hydrogen vehicle is an alternative fuel vehicle that uses hydrogen as its onboard fuel for motive power. The term may refer to a personal transportation vehicle, such as an automobile, or any other vehicle that uses hydrogen in a similar fashion, such as an aircraft. The power plants of such vehicles convert the chemical energy of hydrogen to mechanical energy either by burning hydrogen in an internal combustion engine, or by reacting hydrogen with oxygen in a fuel cell to run electric motors. Widespread use of hydrogen for fueling transportation is a key element of a proposed hydrogen economy.

Fuel cells produce energy from hydrogen by?
the fuel cells convert hydrogen into energy using a converter and that energy is used to power the vehicle
What is the fuel used in a fuel-cell automobile?
Fuel cells come in many varieties. Low-temperature designs such as proton exchange membrane fuel cells [PEMFC's, also known as polymer electrolyte membrane fuel cells] are mostly aimed at portable and transport applications
Has hydrogen fuel cells been used as energy yet?
Hydrogen fuel cells powered the Apollo space craft of the 1960's. They're also used today as large power plants for rural areas
What fuel is used in a fuel cell automobile engine?
Fuel cells operate by combining hydrogen and oxygen without actual combustion as in gasoline engines. A catalyst separates the electrons and protons to combine the elements. (Some versions of fuel cells are high-temperature only.) Hydrogen gas
Are fuel cells a fossil fuel?
Fuel conversion cells are made from platinum and convert the material going through the device into heat and electric power (about equally). The element used is often hydrogen. Hydrogen comes from many places, but the practical commercially viable method in use is from stripping all other elements from natural gas. This means that the hydrogen used in most applications is a fossil fuel. This does not mean it must be this way though. Hydrogen could be obtained through the chemical stripping of water into hydrogen and oxygen. This would make fuel cells non fossil fuel based.
Are fuel cells a renewable or non renewable source of energy?
Fuel cells are a manufactured item and are not renewable. The fuel that is used in the fuel cells can either be renewable (alcohol, methane from waste digestion,hydrogen from wind or solar conversion of water) or non-renewable (Hydrogen or methane from oil and gas production, alcohol from industrial processes)
How are astronauts provide enough water while on there misson?
The Apollo spacecraft used fuel cells to create electricity. To do this fuel cells combine Hydrogen and Oxygen and the byproduct is H2O...water.
What are the two gases used to produce electricity in fuel cells?
The two gases used to produce electricity in fuel cells are hydrogen (H2) as the fuel and oxygen (O2) as the oxidant. In a fuel cell, hydrogen is fed to the anode (negative electrode) and oxygen is supplied to the cathode (positive electrode), where they react to produce water, heat, and electricity through an electrochemical process called the oxidation-reduction reaction.
Hydrogen fuel cells combine hydrogen and oxygen to produce water and energy Assume 1 kg of fuel is used and the mass of the water produced is 1.10 x 10-11 kg How much energy is produced by this fuel?
do the math
Why liquid hydrogen cannot be used as a fuel?
Liquid hydrogen IS used as a fuel. It's used in rockets - and some cars.
What is a hydrogen fuel cell used for?
The application range of hydrogen fuel cells includes automobiles, forklifts, airplanes, boats, submarines, fueling stations, power generation, hybrid vehicles, notebooks, smartphones and many others.
What are some usages for hydrogen?
Hydrogen can be used as fuel.
