Recently, the new generation of alkaline electrolyzer (QQSD-Z series) independently developed by Shanghai Bright-H Technology Co., Ltd (hereinafter Bright-H Technology) passed the performance and stability tests and acquired the third-party certification from TüV Rheinland.
Maximum operating current density up to 10,000 A/m2
DC power consumption as low as 3.77 kwh/Nm3 @2,500 A/m2
Load range reaches 20-167%
Reduce the overall cost of hydrogen production by 13%
Current density exceeds 10,000 A/m2
DC power consumption as low as 3.77 kwh/Nm3
Bright-H Technology has been deeply engaged in independent research and development of green hydrogen technology for a long time, and this new product introduces groundbreaking technological reforms, such as flow field optimization, micro-flow channel and innovative design of gas diffusion layer structure, etc., which significantly reduce the internal resistance, and still can achieve a significant leap in performance when continuing the use of traditional low-cost non-precious metal catalysts and diaphragm materials.
At the maximum load of 167%, the current density is 10,000 A/m2, the DC power consumption is only 4.69 kWh/Nm3, the concentration of hydrogen in oxygen is 1.38%, while the concentration of oxygen in hydrogen is 0.13%.
At a low load, when operating at a current density of 2,500 A/m2, the DC power consumption is only 3.77 kWh/Nm3, the hydrogen concentration in oxygen is 1.65%, and the oxygen concentration in hydrogen is 0.24%.
The above excellent performance means that the DC power consumption of alkaline electrolytic water hydrogen production by Bright-H Technology has officially entered the 3.0 era, leading the industry in terms of energy efficiency improvement and promoting the large-scale development of green hydrogen industry.
Stable operation at high rated operating conditions
The new QQSD-Z series electrolyzers have a rated current density of up to 6,000 A/m2 and a DC power consumption of only 4.26 kwh/Nm3, and show no voltage decay after more than 1,000 consecutive hours of stability testing. The product combines advanced sealing materials and structural design for high fluctuation compatibility with wind and green power, resulting in a large reduction of hydrogen concentration in oxygen. Especially in the long-term operation under low load conditions, the hydrogen concentration in oxygen is always kept below 2%, and the oxygen concentration in hydrogen is lower than 0.3%, which greatly improves the safety and stability of the electrolyzer, and effectively solves the bottleneck of wind-generated direct-connected off-grid hydrogen production.
QOSD-Z series new electrolyzers developed by Bright-H Technology, the leader of electrolytic water hydrogen production equipment technology in China, covers a scale of 50 - 2000 Nm3/h, which can meet the needs of various application scenarios and provide users with high-efficiency, high-reliability and low-cost electrolytic water hydrogen production products. This new product release is not only the result of Bright-H Technology's long-term research and development in green hydrogen technology and unremitting innovation, but also marks that China's independently developed alkaline electrolyzer technology has reached a new height.
