Resumen de: US2025171910A1
This invention discloses a method, device, and system for the direct electrolysis of seawater without desalination for hydrogen production. By immersing the direct electrolysis device for hydrogen production from seawater without desalination directly into seawater, driven by the pressure difference at the interface between seawater and the self-driven electrolyte, seawater continuously enters the device through the solution mass transfer layer. The self-driven electrolyte induces the water to enter the electrolyte solution, while the hydrophobic action of the solution mass transfer layer effectively blocks non-water impurities in the solution. During electrolysis, the water in the self-driven electrolyte is consumed to produce hydrogen and oxygen, inducing the regeneration of the electrolyte, maintaining the pressure difference at the interface, and achieving a self-circulating excitation drive without additional energy consumption.
