SOLAR OPTOTHERMAL COUPLED HIGH-TEMPERATURE WATER ELECTROLYSIS HYDROGEN PRODUCTION SYSTEM

摘要

A solar optothermal coupled high-temperature water electrolysis hydrogen production system comprising a heat energy supply module (20), a hydrogen production and separation module (21) and a storage module (22) which are sequentially connected; the heat energy supply module (20) comprises a light concentrating device (1), a heat collection device (2), a heat storage high-temperature heat pipe heat exchanger (3) and a heat exchanger unit (19) which are sequentially connected, and hydrogen and oxygen are separated by electrolysis after a water and hydrogen mixture in the hydrogen production and separation module (21) is heated into a steam and hydrogen mixture above 800°C. Compared with the prior art, the hydrogen production system does not need to consume fossil energy, has a more green and environmentally friendly production process, and greatly reduces the power consumption; a stable heat source is provided by the system, the problem that a photo-thermal system is not stable due to changes in the weather is solved, the availability of the system is improved, and meanwhile the electrolytic efficiency of the system is improved.
