Abstract
In this paper, a method of efficient hydrogen production using low-power electrolysis based on pre-magnetic polarization was proposed in order to improve the rate of hydrogen production by water electrolysis, with reduced energy consumption, molecular polarity, and stress–strain characteristics of distilled water under the condition of a pre-magnetic field. By constructing a microphysical model of hydrogen proton energy-level transition and a macroscopic mathematical model corresponding to magnetization vector-polarization hydrogen proton concentration in the pre-magnetic field, the ionic conductivity, electrolyte current density, interelectrode voltage, and hydrogen production efficiency under a varying magnetic field were qualitatively and quantitatively analyzed. In addition, an adjustable pre-magnetic polarization hydrolyzing hydrogen production test platform was set up to verify the effectiveness of the proposed method. The repeated test results, within a magnetic field strength range of 0–10,000 GS, showed that the conductivity of distilled water after pre-magnetic polarization treatment increased by 2–3 times, the electrolytic current density of the PEM (Proton Exchange Membrane) increased with increasing magnetic field strength, the voltage between the poles continuously decreased, and the hydrogen production rate was significantly improved. When the magnetic field strength reached 10,000 GS, the rate of hydrogen production by the electrolysis of distilled water increased by 15–20% within a certain period of time.

Summary
To cope with the challenges of climate security and to promote the low-carbon, green, and sustainable development of the global economy, China, the European Union (EU), Japan, South Korea, and several other major economies have successively announced their own carbon neutrality goals; the carbon reduction and decarbonization process of the energy industry will be further accelerated. Hydrogen production by water electrolysis has been widely noted by the majority of scientific research institutions and scholars for its advantages of having rich raw materials, as well as being green, clean, and low-carbon [3,4]. Faced by the development of hydrogen production by water electrolysis technology at present are its high energy consumption and low energy-exchange efficiency. A large number of scientific research institutions and scholars have begun to study the changes in various physicochemical characteristics in water electrolysis, and adopted various auxiliary methods such as super gravity [6], ultrasonic [7], and magnetic fields [8], attempting to mitigate the above problems by enhancing the performance of electrolytic cells [9]. This study can supplement and improve the existing hydrogen production using the water electrolysis system, and provides a new idea for efficient hydrogen production using low-power electrolysis
