In the critical period of global energy transition, Sany Hydrogen Energy leads the industry wind vane with its excellent innovation ability and profound technical background. Its newly developed square electrolyzer redefines the appearance and function of hydrogen electrolysis equipment with its unique design language. Its compact square structure not only optimizes the use of space, but also shows Sany's deep understanding and forward-looking layout for the future of hydrogen energy technology.
Performance by the numbers
Hydrogen production capacity: The scale of hydrogen production of single unit is up to 3000Nm³/h, which can easily meet the demand of large-scale hydrogen energy.
Operation density and energy consumption: low energy consumption and high output, the operation density is leading in the industry, up to 12000A/m². At 2500A/m², the energy consumption is as low as 3.95kWh/Nm³.At 10,000A/m², the energy consumption is only 4.5kWh/Nm³.
Load range: Wide power fluctuation range from 5% to 120%, comparable to the scenery applicability of PEM electrolyzer.
Stability: Modularized design and pre-assembled plug-in maintenance ensures long-term stable operation with more than 8,000 hours of annual working hours.
Operation with pressure: working pressure of 0.5MPa, enhancing the adaptability of the system scenario and reducing the need for secondary pressurization.
Disassembly and maintenance: single small chamber replacement can be realized within 2 hours, and tank maintenance downtime can be restarted within 36 hours.
Current efficiency: low stray current, current efficiency over 95%.

Science and technology lead the way to break through barriers
Compound Zero Pole Pitch Technology: Significantly reduces electrolytic solution resistance.
High-efficiency precious metal electrode & low surface resistance composite diaphragm application: Ensure low DC power consumption under high electric density.
Dual hydraulic cylinders automatic synchronization control & mechanical joint fastening technology: High-strength support frame of the extruder ensures structural stability and sealing reliability.
Electrolysis chamber independent circulation technology: the cathode and anode of each electrolysis chamber enter and exit the liquid separately, which greatly improves the uniformity of the flow field and temperature field inside the tank.

The future is here, the scenarios are infinite
Energy conversion: as an energy carrier, it is more suitable to be used in wind and green power hydrogen production base (wide fluctuation range).
Transportation: Applied in hydrogen production and hydrogen refueling integrated station to help green travel (qualified hydrogen purity throughout).
Industrial application: applied to hydrogen production in chemical industry, metallurgy and other industries to promote industrial upgrading (long stable working time).
With the continuous maturity of upstream and downstream technologies and continuous policy support, the economy of Sany Hydrogen's square electrolyzer will be gradually highlighted and usher in a broader market space. At present, a number of well-known enterprises will cooperate with Sany Hydrogen Energy to deploy square electrolyzer hydrogen production demonstration projects.
In the future, Sany Hydrogen will continue to focus on the "3+1" technology route of round electrolyzer, square electrolyzer, Proton Exchange Membrane electrolyzer and BOP, and continue to improve and strengthen the seven core competencies, including integrated design, material R&D, simulation and analysis, test and verification, electrical control, manufacturing process and hydrogen safety design. Sany Hydrogen Energy is looking forward to working with Sany Hydrogen Energy Meanwhile, Sany Hydrogen looks forward to deepening cooperation with industry customers, design institutes, suppliers, research institutes, industry organizations, etc., to seek for the high-quality development of hydrogen energy equipment, and to contribute to the realization of the goal of "Double Carbon" with Sany's strength and Sany's solutions.
