Scenario of Electrolytic Water Hydrogen Production

Electrolytic water hydrogen production is a technology that decomposes water into hydrogen and oxygen with direct current. The core equipment includes electrolytic cell and rectifier power supply. The latter converts grid or new energy alternating current into stable direct current. Electrolytic cell electrode is oxidized by anode and oxidized by cathode under the action of DC. This process is applicable to the production of green hydrogen and can be combined with renewable energy sources to achieve zero carbon emission. The electrolytic water hydrogen production power supply converts AC power into HVDC power to drive the reaction, accurately meeting the voltage and current density requirements of electrolytic cell. It is the "energy hub" for green hydrogen production. Its technical upgrading determines the efficiency and economical efficiency of hydrogen production. In the future, it will develop towards high efficiency, high adaptability and high intelligence, support large-scale hydrogen production from renewable energy sources and help global carbon neutralization.

Uninterruptible power supply for electrolytic water hydrogen production

The product strictly complies with international and industrial standards such as IEC6247-1 (Safety Requirements for Power Electronic Converters) and GB/T 36282 (Technical Specification for Electrolytic Water Hydrogen Production System), integrates anti-reverse current protection, dual magnetic isolation design and modular redundant backup functions, adapts to PV/wind power grid interface and intelligent electrolytic cell linkage system, and supports off-grid/grid hybrid hydrogen production mode. The products cover silicon controlled series power supply and silicon carbide (SiC) series power supply, and the power covers 76kW to megawatt customized demands. They are widely used in green hydrogen integration projects, chemical synthesis, hydrogen energy transportation, semiconductor manufacturing and other fields to achieve efficient, safe and low-carbon hydrogen production.
