Abstract
The present invention relates to a hydrogen recycling flight system and flight method, the hydrogen recycling flight system including: a flight fuselage which has at least one pair of wings at each of both sides of a body; a hydrogen gas balloon which is air-tightly connected to the flight fuselage; a hydrogen fuel cell which is connected with the hydrogen gas balloon and is installed outside or inside the flight fuselage; and a secondary battery which is charged with electricity generated from the hydrogen fuel cell, electricity generated from a solar cell provided at an outer peripheral portion of the flight fuselage, or electricity of an external power network, in which by using a switch, the hydrogen fuel cell is switched to a water electrolysis device or the water electrolysis device is switched to the hydrogen fuel cell, the hydrogen recycling flight system includes: a water tank which stores water generated from the hydrogen fuel cell; the water electrolysis device which electrolyzes the stored water; a switch control device which switches functions of the hydrogen fuel cell and the water electrolysis device; and a high-pressure gas barrel which high-pressure stores hydrogen gas and oxygen gas generated in the water electrolysis device, and the flight fuselage flies by controlling the volume of the hydrogen gas balloon that is flotation power of a flight vehicle by an operation of the hydrogen fuel cell or the high-pressure gas barrel.
