SYSTEM FOR CRYOGENIC STORAGE AND SUPPLY OF REAGENTS FOR POWER PLANT WITH ELECTROCHEMICAL GENERATORS Russian patent published in 2020 - IPC H01M8/06 F17C3/00 

FIELD: cryogenic storage systems.

SUBSTANCE: invention relates to systems for cryogenic storage and supply of reagents (CSSR), namely to systems for cryogenic storage and supply of liquid hydrogen and liquid oxygen on submarines and underwater vehicles (UV) with power plants based on electrochemical generators. Proposed technical solution for CSSR in power module of UV allows to produce CSSR with minimum dimensions and weight of structure, and the design of the oxygen container in the form of a hollow container of annular shape, inside which the hydrogen container is installed, ensures minimum heat inflows from the outside, which considerably increases storage time of cryogenic hydrogen without energy costs for its cooling or insignificant evaporation without increase of pressure inside container due to its minimum consumption in modes of UV movement. Inner sealed cavity of external vacuum housing, in which tanks for hydrogen and oxygen are arranged, is made with screen-vacuum insulation, wherein the oxygen tank is equipped with side untight heat-conducting partitions covering the hydrogen tank, forming an additional heat-insulating screen.

EFFECT: longer storage life of cooled hydrogen is technical result of invention.
