What is a limitation of hydrogen fuel cells?

• A. The infrastructure for producing, storing, and distributing hydrogen is still in development.
• B. They generate large amounts of solid waste.
• C. They operate only in high-temperature environments.
• D. They cannot be used for any electrical generation.

Answer: (A)

Hydrogen fuel cells convert hydrogen and oxygen into electricity with water as the main byproduct. The key limitation is the lack of a complete, practical infrastructure to support hydrogen: producing it, storing it safely, and distributing it to users. Building enough hydrogen production facilities, safe high-pressure or cryogenic storage options, and a widespread network of fueling stations requires huge investments and careful safety planning. Without that infrastructure, fueling a hydrogen-powered system isn’t convenient or cost-effective, which slows adoption even if the fuel cell technology itself is efficient and clean. Hydrogen fuel cells don’t produce solid waste; they mainly emit water vapor and heat. They can operate across a range of temperatures depending on the type, and they are used for both electricity generation and propulsion, so the other options don’t fit.
