Engineers have completed flight tests of a Russian-designed drone based on hydrogen fuel cells.
The power of the two batteries powering the drone is one kilowatt each. The power plant can provide up to 2.5 hours of continuous flight of the device, according to the developers’ notes, the head of the laboratory of solid-state electrochemical systems of the Federal Research Center for Problems of Chemical Physics and Medical Chemistry of the Russian Academy. Sciences Alexei Levchenko. A drone with a takeoff weight of up to 15 kilograms can carry a payload of about two kilograms and can fly at speeds of up to 50 kilometers per hour.
Russian-designed compact and high-capacity fuel cells derive energy from chemical reactions between two groups of chemicals, hydrogen and oxygen. According to Russian experts, these are several times more energy efficient than all existing lithium-ion batteries and other conventional power sources and can operate at sub-zero temperatures. In addition, hydrogen fuel cells are absolutely environmentally friendly – during operation they only emit distilled water vapors, which you can drink, emphasizes Dmitry Grebtsov, head of the MIPT Advanced Energy Laboratory.
