The team developed a prototype power supply based on a chemical hydrogen generator, characterized by an energy capacity of 400 W*h/kg (power supply and six replaceable cartridges), which is 2 times higher than lithium-ion batteries. Electricity is generated by converting hydrogen into electricity using hydrogen fuel cell technology. Hydrogen is supplied from a chemical source of hydrogen as a result of hydrolysis of magnesium hydride powder.
Characteristics of a portable power source:
- output power of 50-100 W
- the output voltage of 12/24 V
- energy reserve in one energy cartridge 650 W*h
- cartridge weight 500 g
- power supply weight 7 kg
- maximum size 50x40x20 cm
Portable power source with a set of 12 cartridges has the weight of a lot less than 13 kg opposite the energy equivalent lithium-ion battery mass of 40 kg (taking in to account capacity Li-Ion battery 200 W*h/kg, which is slightly higher than the most common serial Li-Ion batteries).
portable power supplies for power supply in isolated conditions;
portable power sources for recharging the battery;
onboard power systems for unmanned aerial vehicles (UAVs) and robotics;
wearable and mobile energy sources;
power supplies for Autonomous technical devices (communications, beacons, radars.
