What is the primary function of fuel cells in an aircraft?

• A. To filter impurities from the fuel
• B. To store the fuel
• C. To deliver fuel directly to the engine
• D. To monitor fuel levels

Answer: (B)

The primary function of fuel cells in an aircraft is to store the fuel. Fuel cells are designed to hold and contain the aircraft's fuel supply safely, ensuring that the fuel is readily available for the engines during flight. Proper storage is crucial for maintaining the integrity of the fuel and preventing contamination. This storage capability allows for controlled fuel delivery to the engine when needed, ensuring optimal performance and safety. While filtering impurities is important for maintaining fuel quality, its primary intent does not involve the core function of storage. Similarly, although fuel delivery to the engine is a crucial operation, the mechanism that accomplishes it involves fuel lines and pumps, rather than the cells themselves, which focus on storage. Monitoring fuel levels is also vital for ensuring adequate fuel supply during flight, but this task is typically managed through different systems, such as fuel gauges, rather than being a function of the fuel cells themselves.
