Storage Solutions for Hydrogen Fuel Cell in


Introducing Alsafe’s Carbon Fiber Composite Cylinders, specifically engineered for fuel cell-powered Unmanned Aerial Vehicles (UAVs) and drones.


These cylinders are designed for use with hydrogen fuel cells, which offer several distinct advantages. Hydrogen fuel cells have a higher energy density than batteries, providing drones with extended flight times. They can be quickly refueled, operate efficiently in low temperatures, and use hydrogen – a clean energy source that can help reduce environmental pollution. This makes our hydrogen fuel cell drones ideal for beyond visual line of sight (BVLOS) operations.
