Energy Density of up to 0.65-0.8Wh per gram. Very Exciting!
Excerpt from Manufacturer's Website
AEROPAK is an ultra-light power supply enabled by fuel cells, designed to increase flight endurance for small electric Unmanned Aerial Systems (UAS). It uses an on-demand hydrogen supply system from a chemical stored in a swappable cartridge.
The special characteristics of AEROPAK-1 allows to reduce weight progressively over the course of a flight, by purging spent fuel during flight. This means the average energy density of the system can increase up to 675Wh/kg for a 2 kg system, weighing 1kg after consuming all of its fuel.
