The invention discloses a liquid hydrogen aircraft storage and supply system and a method thereof. According to the liquid hydrogen aircraft storage and supply system, the low-temperature strong paramagnetism of oxygen molecules and the diamagnetism of nitrogen molecules are utilized, a double-section type oxygen-enriched structure with the oxygen-nitrogen separation capacity gradually improved is designed, high-oxygen-content air is obtained, and the operation efficiency of a hydrogen-air fuel cell is greatly improved; and meanwhile, the product water of the hydrogen-air fuel cell and the oxygen-deficient air are subjected to heat and mass transfer to generate a refrigeration effect and then are emptied, so that the cooling efficiency of the air is improved. According to the invention, efficient and continuous supply of hydrogen and air of the hydrogen-air fuel cell in the liquid hydrogen aircraft can be realized, and the operation stability of the hydrogen-air fuel cell is ensured; the air is continuously cooled by using a dew-point indirect evaporative cooler and a liquid hydrogen vaporizer, so that the volume susceptibility of oxygen molecules in the air is enhanced; and the designed oxygen-nitrogen separator is simple in structure, stable in performance, beneficial to miniaturization, light weight and integrated design and capable of meeting the technical requirements of aviation parts.
