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.
What else can I help you with?
Can you use hydrogen peroxyde in a fuel cell?
Hydrogen peroxide can be used in certain types of fuel cells called direct borohydride fuel cells. In these fuel cells, hydrogen peroxide is used as an oxidant in place of oxygen. However, the efficiency and practicality of using hydrogen peroxide in fuel cells is still being researched and developed.
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
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
Does energy used by fuel cells come from the sun?
Yes, the energy used by fuel cells can ultimately be traced back to the sun, especially when the hydrogen used in fuel cells is produced through renewable methods like electrolysis powered by solar energy. In this process, solar energy is converted into electricity, which splits water into hydrogen and oxygen. This hydrogen can then be used in fuel cells to generate electricity. Therefore, while fuel cells themselves do not directly use sunlight, their energy source can be solar-based.
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 is the main element used in fuel cells?
The main element used in fuel cells is typically hydrogen, which is combined with oxygen to produce electricity through an electrochemical reaction.
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
What is the waste product of fuel cells?
The waste product of fuel cells is typically water and heat. When hydrogen is used as the fuel source, the only byproducts are water vapor and heat, making fuel cells a very clean and efficient energy source.
Where are some places hydrogen fuel cells are used?
Hydrogen fuel cells are used in various applications, including transportation, where they power fuel cell vehicles like buses, trucks, and passenger cars. They are also employed in stationary power generation for backup power systems and renewable energy integration. Additionally, hydrogen fuel cells are utilized in industrial settings, such as forklift operations in warehouses, and in aerospace for powering spacecraft.
What can you make with hydrogen?
Hydrogen can be used to produce electricity in fuel cells, used as a clean fuel for transportation in hydrogen cars, and utilized in ammonia production for fertilizers. It is also used as a reducing agent in metal refining processes.
How can hydrogen be used as a fuel source?
Hydrogen can be used as a fuel source by being converted into electricity through a fuel cell. This process involves combining hydrogen with oxygen to produce electricity, with water and heat as byproducts. Hydrogen fuel cells are used in various applications, such as powering vehicles and providing backup power in remote locations.
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.
