Disclosed in the present invention are a seawater non-desalination in-situ direct electrolysis hydrogen production method, apparatus, and system. The seawater non-desalination in-situ direct electrolysis hydrogen production apparatus is directly immersed in seawater. Pushed by an interface pressure difference between the seawater and a self-driving electrolyte, the seawater continuously enters the seawater non-desalination in-situ direct electrolysis hydrogen production apparatus by means of a solution mass transfer layer, and is induced into an electrolyte solution by the self-driving electrolyte inside the apparatus. Meanwhile, a hydrophobic effect of the solution mass transfer layer can effectively block non-aqueous impurities in the solution. During electrolysis, water in the self-driving electrolyte is consumed to prepare hydrogen and oxygen and induce electrolyte regeneration, thereby maintaining the interface pressure difference, and achieving self-circulation excitation drive without additional energy consumption. When the amount of water solution induced by the self-driving electrolyte is equal to the amount of water consumed by the electrolytic hydrogen production, a dynamic and stable seawater non-desalination in-situ direct electrolysis hydrogen production method and system having no additional energy consumption are achieved.
