Title:
DESALINATION-FREE IN-SITU DIRECT ELECTROLYTIC HYDROGEN PRODUCTION DEVICE FOR NON-PURE-WATER SOLUTION, AND USE METHOD
Document Type and Number:
WIPO Patent Application WO/2024/046397
Kind Code:
A1
Abstract:
Disclosed in the present invention are a desalination-free in-situ direct electrolytic hydrogen production device for a non-pure-water solution, and a use method. The desalination-free in-situ direct electrolytic hydrogen production device comprises an electrolysis system, a water vapor mass transfer layer, a collecting device and a containing device for containing a self-driving electrolyte solution, wherein the water vapor mass transfer layer isolates the electrolysis system from a non-pure-water solution to be electrolyzed, and the water vapor mass transfer layer can make water molecules of said non-pure-water solution enter the electrolysis system by means of phase change migration and can prevent solid and liquid substances in the non-pure-water solution from passing through; and the collecting device is in communication with the electrolysis system and is used for respectively collecting hydrogen and oxygen generated by electrolysis. The present invention solves the problems of incapability of in-situ hydrogen production due to space-time limitations, low electrolytic efficiency, high energy consumption, great increase of cost, catalyst corrosion, membrane blockage, etc., in the existing direct hydrogen production technology for a non-pure-water solution.
