UAV Hydrogen Fuel Cell

This fuel cell from Intelligent Energy is a clean energy efficient alternative to lithium-ion batteries. It runs on only hydrogen and air and allows the drone to stay up in the air for a lot longer period than batteries can, plus it can be refuelled in only a couple of minutes to get you back in the air quicker. Perfect for search and rescue drones or even future delivery drones like the ones planned by Amazon.
Intelligent Energy’s air cooled fuel cell systems run on hydrogen and ambient air to produce clean DC power in a simple, cost-effective, robust and lightweight package. They have a higher energy to mass ratio than battery based systems and can be refuelled in a few minutes.
