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.
Excerpt from Isreal's Homeland Securty Home
A cooperation between Israel and Singapore has resulted in a breakthrough in powering unmanned air systems. “This will change the world of UAVs and opens many new paths for using them in many applications” an Israeli source said.
Comments
Aeropack is a great product, but especially for fixed wing.
The fuel cell systems may have, even with a buffer lipo battery, low rate of discharge with respect to their capacity.
So for rotorcraft systems are difficult to use, unfortunately
