What is the use of hydrogen oxygen fuel cell?

Hydrogen fuel cells combine hydrogen and oxygen, creating nothing but pure water as exhaust. By converting the chemical energy stored in the gasses into electrical energy, the energy can be harnessed to power electric drive motors, temporary storage batteries, or a variety of other end applications.

What is the most popular application of hydrogen fuel cell?

Which of the following is the most popular application of hydrogen fuel cell? Explanation: Spacecraft propulsion uses hydrogen as fuel with the help of fuel cells. It is one of the most established techniques to deploy spacecrafts into outer-space.

What is fuel cell and its applications?

Fuel cells are used for primary and backup power for commercial, industrial and residential buildings and in remote or inaccessible areas. They are also used to power fuel cell vehicles, including forklifts, automobiles, buses, boats, motorcycles and submarines.

What are the main uses of hydrogen?

Hydrogen: uses

• commercial fixation of nitrogen from the air in the Haber ammonia process.
• hydrogenation of fats and oils.
• methanol production, in hydrodealkylation, hydrocracking, and hydrodesulphurization.
• rocket fuel.
• welding.
• production of hydrochloric acid.
• reduction of metallic ores.

What is the most important use of hydrogen?

Following are some important uses of hydrogen:

• Hydrogen is used in the synthesis of ammonia and the manufacture of nitrogenous fertilizers.
• Hydrogenation of unsaturated vegetable oils for manufacturing vanaspati fat.
• It is used in the manufacture of many organic compounds, for example, methanol.

Why is a hydrogen fuel cell an alkaline fuel cell?

Alkaline fuel cells consume hydrogen and pure oxygen, to produce potable water, heat, and electricity. They are among the most efficient fuel cells, having the potential to reach 70\%.

Where is hydrogen used as a fuel?

It can be used in fuel cells or internal combustion engines (see HICEV). Regarding hydrogen vehicles, hydrogen has begun to be used in commercial fuel cell vehicles, such as passenger cars, and has been used in fuel cell buses for many years….Bibliography.

What are the uses for oxygen?

Common uses of oxygen include production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving.

How do hydrogen fuel cells work?

A fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode. In a hydrogen fuel cell, a catalyst at the anode separates hydrogen molecules into protons and electrons, which take different paths to the cathode. The electrons go through an external circuit, creating a flow of electricity.

What are uses for oxygen?

How does hydrogen fuel cell technology work?

Hydrogen fuel cells combine hydrogen and oxygen, creating nothing but pure water as exhaust. By converting the chemical energy stored in the gasses into electrical energy, the energy can be harnessed to power electric drive motors, temporary storage batteries, or a variety of other end applications.

How can hydrogen and oxygen be used to generate electricity?

The reaction between hydrogen and oxygen can be used to generate electricity via a fuel cell. Such a cell was used in the Apollo space programme and it served two different purposes – It was used as a fuel source as well as a source of drinking water (the water vapour produced from the cell, when condensed, was fit for human consumption).

What are the applications of hydrogen power in transportation?

Hydrogen power is being considered for other public transportation applications, including hydrogen fuel cell buses. Several major cities including Chicago, Vancouver, London, and Beijing have experimented with hydrogen powered buses. 4. Trains

What does NASA use hydrogen for?

NASA uses hydrogen to supply fuel for space flight, transportation and electrical power. NASA has used hydrogen gas as rocket fuel for decades. Through the Centaur, Apollo and Space Shuttle Programs, NASA has become expert at handling hydrogen safely and effectively. NASA – Summary: Space Applications of Hydrogen and Fuel Cells
