Focusing on the core issue of "how to achieve low-load operation of alkaline water electrolysis hydrogen production equipment", Lv Guoai, executive vice president of CIMC, made a detailed technical release report, focusing on the core issue of "how to achieve low-load operation of alkaline water electrolysis hydrogen production equipment", and analyzed the safeguard measures and underlying technologies of CIMC to achieve the minimum load operation of electrolyzer hydrogen production equipment from four dimensions: reasons, solutions, empirical data and application products.
Lv Guoai pointed out in the technical release report that when the electrolyzer is running at low load, the hydrogen in the oxygen will rise rapidly and exceed 18% safety limit, will bring the most risk. The key to achieving stable operation of the alkaline electrolyzer under low load conditions is the control of "hydrogen in oxygen" in the tank.
The core technical team of current collector led by Lv Guoai focuses on four external operating factors (operating load, system pressure, electrolyte circulation and hydroxide-oxygen pressure difference) and four internal influences** (parasitic electrolysis, dissolution mixing, diaphragm penetration and pressure leakage) that affect gas purity. It adopts a variety of technologies and technological means, such as optimization of the polar frame structure, composite electrode technology, SS-WAC post-treatment process, and increasing the current density under the reliable membrane electrode (pure nickel electrode + PPS separator) system, which solves the problem of excessive hydrogen in oxygen under low load.
Lv Guoai, Executive Vice President of CIMC, released the low-load operation water electrolysis hydrogen production technology.
CIMC uses the combination technology of "high-efficiency Rainey nickel electrode", "composite electrode flexible flow field" and "variable frequency liquid regulation" to manufacture a low-load hydrogen production demonstration electrolyzer, and the third-party performance test is completed by Bureau Veritas China. Test data were presented at the press conference, and the hydrogen content in oxygen was only 1 when the minimum operating load of the demonstrated electrolyzer was achieved at 20%.24%。
At the press conference, Liu Zhongyong, Director of Hydrogen Energy Business of Bureau Veritas China, announced the CIMC empirical electrolyzer test data to the guests and issued a third-party performance certificate.
Bureau Veritas China issued a third-party performance certification for low-load hydrogen production to CIMC.
Lv Guoai said that the low-load operation hydrogen production combination technology released this time will be fully applied to CIMC-GH series 100 square electrolyzer products; At the same time, this combination technology has also been implanted in the product design of the upcoming 2000 standard square electrolyzer. Through the pure nickel electrode and PPS separator, it is equipped with SSWAC inverter liquid conditioning post-treatment system, which fully realizes the stable and low-load operation of the large standard square electrolyzer.
At the seminar, Professor Xing Wei of Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Professor Chen Xinde of Guangzhou Institute of Energy, Chinese Academy of Sciences, and Ding Jianning, President of Yangzhou University, delivered keynote reports on the themes of "integration of wind, solar and hydrogen storage", "off-grid scale hydrogen production from renewable energy" and "green methanol", pointing out that in order to meet the industry needs of large-scale off-grid hydrogen production from renewable energy, broadening the range of operating load fluctuations of electrolyzers is a common problem faced by the water electrolysis hydrogen production industry, and it is also the core technology required for the development of the industry.
