What are the pros and cons of hydrogen fuel cells?

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.

Can a hydrogen fuel cell explode?

Hydrogen used in the fuel cells is a very flammable gas and can cause fires and explosions if it is not handled properly.

What are the disadvantages of hydrogen fuel cells?

List of the Disadvantages of Hydrogen Fuel Cells 1. Hydrogen fuel cells can still pose health risks. 2. It is not an affordable technology for the average person. 3. Hydrogen fuel cells are available in limited quantities. 4. It requires a huge capital investment to incorporate into our infrastructure.

What are the uses of hydrogen fuel cells?

Combustion generates plenty of energy. Hydrogen fuel cells generate electricity from oxygen and hydrogen. These electrochemical cells generate only water vapor so it is considered as environment friendly. Fuel cells are used in spacecrafts, remote weather stations and submarines. When in liquid form, it is used as rocket fuel.

Do fuel cells require hydrogen and oxygen?

Both hydrogen and oxygen are required for a fuel cell to create electricity. Together, they combine to create water, which is drained from the cell. One fuel cell wouldn’t be enough to power anything like a boiler or a vehicle. Instead, individual fuel cells are assembled together to form what’s known as a stack.

How does a fuel cell create hydrogen?

Rather than storing chemical energy inside itself, a hydrogen fuel cell receives a supply of chemical energy from the outside. This chemical energy is stored in the hydrogen that is supplied to the anode of the fuel cell. The hydrogen ions (protons) that are produced from the hydrogen at the anode travel through the electrolyte in the fuel cell to the cathode.
