Abstract

See full text

The invention concerns a system (1) for producing dihydrogen comprising: —a high-temperature electrolyser (2) suitable for implementing steam electrolysis at a temperature greater than 500° C. and producing a mixture of steam and dihydrogen; —a dihydrogen compressor (3); —a main water and dihydrogen circuit (10) on which at least an evaporator (11), the high-temperature electrolyser (2), a condenser (E3) and the compressor (3) are arranged in succession, a first heat exchanger (E1) bringing the steam from the evaporator (11) and the mixture of steam and dihydrogen from the high-temperature electrolyser (2) into heat exchange so as to superheat the steam from the evaporator (11); the system being characterised in that—the compressor (3) is a chemical compressor supplied with heat by heat exchange with the condenser (E3); —the condenser (E3) is disposed directly at the outlet of the first exchanger (E1).
