What are some applications of hydrogen fuel cells?

• A. They can power vehicles and provide stationary power generation for homes and buildings.
• B. They are used only in industrial chemical processing.
• C. They power only small portable devices.
• D. They are used exclusively in space missions.

Answer: (A)

Hydrogen fuel cells generate electricity by combining hydrogen with oxygen, with water vapor as the main byproduct. This makes them versatile for two broad use cases. In transportation, they can power electric motors in cars, buses, trucks, and forklifts, offering clean, quiet operation and rapid refueling compared with many batteries. In stationary power, they can provide reliable electricity for homes, buildings, and facilities—either as a primary power source, backup power, or part of a microgrid that complements renewable energy sources. Their ability to scale from small to large outputs and to integrate with renewables is what makes them practical for both moving people and generating steady power on site. The other options don’t capture this wide range of real-world deployments, since hydrogen fuel cells aren’t limited to industrial processing, tiny portable devices, or exclusive space use.
