What are the applications of hydrogen fuel cell?
Fuel cells can be used in a wide range of applications, including transportation, material handling and stationary, portable, and emergency backup power. Hydrogen can be used in fuel cells to generate power using a chemical reaction rather than combustion, producing only water and heat as byproducts.
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 are the major potential applications of fuel cells?
Why Study Fuel Cells Fuel cells can be used in a wide range of applications, providing power for applications across multiple sectors, including transportation, industrial/commercial/residential buildings, and long-term energy storage for the grid in reversible systems.
Where are hydrogen fuel cells used today?
Stationary hydrogen fuel cells are the largest and most powerful fuel cells. They are a clean, reliable source of power to cities, towns, and buildings. These fuel cells are also used for back-up and remote power applications including remote weather stations and rural locations.
Which of the following is a disadvantage of using hydrogen fuel cells?
1) Although Hydrogen cells are being used to power hybrid cars, it’s still not a feasible source of fuel for everyone. It is expensive. 2) The transport and storage of Hydrogen, even in small amounts is difficult. 3) As of the moment the present infrastructure supports gasoline, replacing it requires refitting.
What are the pros and cons of hydrogen fuel?
Hydrogen fuel cells Pros: No vehicle emissions other than water vapor. Fuel economy equivalent to about twice that of gasoline vehicles. Hydrogen is abundant, and can be made from renewable energy. Cons: This space-age technology is expensive.
What is the lifespan of a hydrogen fuel cell?
The fuel cell stacks are designed to last the lifetime of the vehicle, about 150,000–200,000 miles. At the end of its lifespan, the fuel cell will be disassembled and the materials recycled, similar to what happens with vehicle components today.
What is the problem with hydrogen fuel cells?
Refueling times are too long. There is a need to develop hydrogen storage systems with refueling times of less than three minutes over the lifetime of the system. Cost. The cost of on-board hydrogen storage systems is too high, particularly in comparison with conventional storage systems for petroleum fuels.
