The invention relates to a micro-flow storage and supply system and method. The micro-flow storage and supply system comprises a gas storage and control module, a propellant storage and supply module and a micro-flow control module. The gas storage and control module adjusts input high-pressure gas to the gas pressure needed by the propellant storage and supply module through a mechanical pressure reduction part, and constant output pressure is provided for the liquid propellant stored in the propellant storage and supply module. The propellant storage and supply module does piston motion under constant output pressure, and the stored liquid propellant is discharged to the micro-flow control module; the micro-flow control module provides preset flow resistance for the system, and the output of the liquid propellant is adjusted to reach the ultra-micro flow of the magnitude of ten nanoliters per second. According to the invention, a certain volume of liquid propellant can be stored for a small spacecraft propulsion system, and nanoliter per second-order flow output can be provided.
