[0002] Hydrogen-powered drones use hydrogen fuel cells as their core power source. The hydrogen they carry is used as fuel to react with naturally inhaled oxygen under the action of a platinum catalyst to produce electricity to drive the drone's flight, truly achieving zero carbon emissions. At the same time, it has the advantages of ultra-long flight time and resistance to low temperatures.
