Diaphragm for Alkaline Electrolysis of Water for Hydrogen Production The history of electrolytic hydrogen production (WE) as an industrial hydrogen production process can be traced back to the 1920s, when the early technology was mainly based on alkaline electrolysis systems. This type of system uses inexpensive nickel based materials as electrodes, employs porous membranes for electrode separation, and uses potassium hydroxide (KOH) solution with a mass fraction exceeding [...]

Resistance of Hydrogen Production System by Water Electrolysis Resistance is a key factor causing energy loss in the process of hydrogen production through hydroelectric electrolysis. According to Ohm's Law, when current passes through a resistor, Joule heat is generated, which cannot be converted into the chemical energy required for hydrogen production, directly reducing the energy efficiency of the system. Therefore, clarifying the composition mechanism of resistors and optimizing [...]

Development of dry cathode AEM electrolysis water technology The anion exchange membrane electrolysis water technology (AEMWE) with dry cathode configuration has demonstrated application advantages in multiple dimensions: its simplified water management system can reduce operational complexity, and its ability to adapt to non corrosive working environments not only reduces equipment corrosion risks, but also significantly reduces capital investment and operating costs, improving technical economy. The core influencing factors [...]
