FIELD: space.
SUBSTANCE: invention relates to space rocket systems and can be used in designing orbital filling complex (PCD) or lunar base. Method includes delivery on PCD of water and obtaining from it by electrolysis hydrogen and oxygen. Said gases are pre-cooled in contact with cold surface of PCD, then compressed and repeatedly cooled and liquefied by throttling and collected in form of liquid fuel components. Water electrolysis processes and compression are performed in turn, pneumatically isolating electrolytic cell from obtained gases. During first compression, hydrogen is first compressed using an electrochemical method, and then said hydrogen is used for compressed of oxygen. After oxygen liquefaction, hydrogen used for compression thereof before throttling is cooled with obtained liquid oxygen to temperature below inversion temperature at given pressure.
EFFECT: technical result is improved manufacturability of liquid rocket fuel, longer storage life on PCD, higher reliability and service life of PCD as a whole.
