Fuel Cell vs. Battery
Electrically powered UAVs typically use Lithium Polymer (LiPo) battery packs as an energy source, which effectively address many of the critical UAV system requirements listed above, all except one: Long Endurance. In fact, this is the main limiting factor for all military or commercial electric UAVs in the market today and hence a significant technology gap exists. Fuel cell systems have the ability to fill this gap and therefore can meet ALL of the key UAV requirements.
