Title:
ELECTROLYZER FOR GENERATING POTENTIAL BY MEANS OF FLOW OF ELECTROLYTE, AND STACK THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/124711
Kind Code:
A1
Abstract:
The present invention implements, as a water electrolysis device for hydrogen production, the principle of generating a kinetic electromotive force in an electrolyte fluid as a magnetic flux becomes a time-varying magnetic flux when an aqueous electrolyte solution flows at a high speed under a transverse magnetic field. Proposed is an electrolyzer that dramatically lowers, as follows, transport resistance, which is a factor that greatly hinders energy efficiency in the conventional water electrolysis method, through a device configuration having a feature in which an electrolyte flows at high speed. Since ions flowing at high speed come into contact with an electrode and react therewith, compared to the conventional water electrolysis, which relies on microscopic ion mobility of only about 10-7m/sec(10-4mm/sec), ion transport is dramatically improved, and thus there is no possibility for ion resistance and electrolyte diffusion resistance. In addition, since gas generated in each flow path through a redox reaction is discharged by means of the speed and pressure of electrolyte flow upon being generated, resistance from bubbles does not occur. On the other hand, cations (H3O+, H+) generated in an anode flow path without a separator are recycled to a cathode flow path, and anions (OH-) generated in the cathode flow path are recycled to an anode flow path. Therefore, no conventional separator resistance occurs, and the ions and pH around each electrode are maintained favorably for a reaction, thereby preventing the occurrence of additional overvoltage.
