What is the role of hydrogen in a hydrogen fuel cell?

• It gains electrons at the cathode.

• It donates electrons at the anode.

• It combines with carbon to form methane.

• It acts as a catalyst for the reaction.

What is the purpose of the air entering a hydrogen fuel cell?

• To provide hydrogen for the reaction.

• To provide oxygen for the reaction.

• To cool the fuel cell.

• To remove excess water.

Which of the following best describes a fuel cell?

• A device that burns fuel to produce heat.

• An electrochemical cell that converts chemical energy into electrical energy.

• A battery that stores electrical energy for later use.

• A device that uses solar energy to produce electricity.

What is the only product of the reaction in a hydrogen fuel cell?

• Carbon dioxide

• Water

• Carbon monoxide

Which of the following is a major disadvantage of hydrogen fuel cells related to hydrogen production?

• Hydrogen is a renewable resource.

• Hydrogen production releases carbon dioxide when derived from fossil fuels.

• Hydrogen fuel cells produce harmful pollutants.

• Hydrogen is easy to store and transport.

Why are hydrogen fuel cells considered renewable?

• They use fossil fuels for production.

• They rely on the electrolysis of water, which is a renewable resource.

• They produce carbon monoxide as a byproduct.

• They require high-pressure tanks for storage.

What is one of the main challenges in storing hydrogen for fuel cells?

• Hydrogen is not flammable.

• Hydrogen storage requires high-pressure tanks, making it difficult and expensive.

• Hydrogen can only be stored in liquid form.

• Hydrogen storage is more convenient than storing liquid petrol.

Which of the following is a limitation of hydrogen fuel cells related to infrastructure?

• Hydrogen fuel cells are not efficient.

• There are very few hydrogen filling stations available.

• Hydrogen fuel cells produce harmful pollutants.

• Hydrogen fuel cells are not renewable.
