Yes, drones can use hydrogen fuel cells: large industrial drones fly on a fuel cell that makes electricity on board from hydrogen and air. The only emission is water.
Which drones it suits
A fuel cell pays off on large multirotor and VTOL drones that fly long missions, need to refuel fast or work in the cold. Refuelling takes about two minutes instead of hours of charging. At system level, our fuel cell systems keep full performance down to −20 °C.
When a battery is the better choice
On small drones and short flights near a charger, a battery is usually simpler.
We make air-cooled PEM stacks from 500 W to 4.8 kW and complete systems from 1 kW. See hydrogen fuel cell drone power.
