Abstract
Disclosed is a small-scale hydrogen liquefaction system using cryocoolers. The system includes: a gas supply line to supply a gaseous hydrogen; n cryocoolers each connected to the gas supply line to be connected in parallel and configured such that the gaseous hydrogen supplied from the gas supply line is divided into n portions, and the n portions flow through the n cryocoolers, respectively, and are cooled to a liquefaction temperature, wherein n is a natural number equal to or greater than 2; n heat exchangers each attached to a cold head of each of the n cryocoolers; and a low-temperature chamber providing an accommodation space to accommodate the n cryocoolers therein.
