What does a fuel cell refer to in aviation?

In aviation, a fuel cell refers to a component specifically designed for fuel storage. These cells are integral to the aircraft's fuel system, as they safely hold the fuel required for the engines while ensuring that it is protected from contamination and structural failures. Fuel cells vary in shape and size based on the specific design of the aircraft, and they can be located in different parts of the aircraft, including the wings and fuselage.

This storage function is critical because it impacts the aircraft's overall weight, balance, and range. Efficient fuel storage enables better distribution and management of fuel as it's used during flight, contributing to overall efficiency and safety. Understanding the role of fuel cells is essential for those studying aircraft fuel systems, as they are foundational elements that affect various operational and engineering considerations in aviation design.
