Authoritative certification lays the industry benchmark

Mr. Ye Jiong said at the ceremony.，Facing the challenge of high volatility of wind and solar energy resources，Ensure the safety and stability of the hydrogen production system、Excellent hydrogen and oxygen purity and wide load operation capability，It has always been a common technical challenge faced by the industry.。Trinity Hydrogen EnergySSeries of square troughs under the strict witness of Bureau Veritas technical specialist.，Demonstrate perfect fit，This is not only a recognition of the technical strength of Sany Hydrogen Energy.，It is also a great progress in the hydrogen production equipment industry.。

Deep cultivation of technology creates six core advantages

Mr. yuan Dan, chairman of Sany Hydrogen Energy, introduced the new generation in detail at the press conference.STechnical breakthrough and excellent performance of series square groove。SSeries Square Slot Wide Load Range、The gas purity in the whole process of startup is up to standard.、Advantages such as convenient operation and maintenance have won wide attention from experts and enterprises attending the meeting.。

SSeries of square slots featuring high current density、Large standard square、Wide load，Integrated with industry-leading composite diaphragm、Noble metal electrode、Pure nickel and other materials。Electrolysis unit adopts zero polar distance design and independent circulation structure.，Continuous improvement of flow field and temperature field simulation，0 is supported.5MPaOperation under pressure，It can realize stable operation of 12000 electric density.。

Wide load range：SSeries Square Groove Load Range Up to 5%-120%，During the Bureau Veritas Certification Test，At 5%~120%The system operates stably in each working condition within the load range.。Especially at 5%Continuous operation with load 4+hIn working condition，Hydrogen purity has been stable at 99.85%Above，Oxygen purity is stable at 99.5%Above。

High efficiency and energy saving：By optimizing the structure and material selection of the electrolysis unit,，SSeries of square grooves while maintaining high current density，Low energy consumption is achieved。At 2500A/m²To 10000A/m²Within the range of electrical security.，DC energy consumption as low as 3.88-4.4 kWh/Nm³，Up to 97% current efficiency%，It sets a new benchmark for the efficient utilization of hydrogen energy.。

Convenient operation and maintenance：The innovative modular design enablesSThe operation and maintenance of the series of square slots become extremely simple.。The replacement of a single electrolysis cell takes only 35 minutes，Total maintenance restart time reduced to 36 hours，This technological innovation has greatly reduced the cost of operation and maintenance and time cost.，Increased availability and reliability of equipment。

Operation under pressure：0 is supported.5MPaOperation under pressure，Ensure the safety of long-term operation while taking into account the downstream pressure demand，Compare with that normal pressure square groove，SA Serie of square slots can significantly reduce that nee for secondary compression,。

Starting the machine is pure，Zero waste：In the warm start、Hot standby startup、Cold start and other working condition certification test，The purity of hydrogen and oxygen is realized, and the product is qualified when the machine is started，No emptying waste in the whole process。

Efficient utilization of green electricity：In the certification of wind and solar fluctuation curve fitting of the Hydrogen Energy Alliance,，SSeries of square cells exhibit excellent dynamic coupling hydrogen production performance，It has strong power variable load capability，The operation power following rate is higher than 90%，Fully competent for the green hydrogen production project of the large base。

Trinity Hydrogen EnergySSuccessful development and certification of the series of square grooves with pressure，It is a milestone for the development of the company itself.。A new generation of SANY hydrogen energySThe technological breakthrough of a series of square troughs with pressure will not only promote the progress of hydrogen energy technology and the upgrading of industry，It will also promote the improvement and expansion of the hydrogen energy industry chain.，To provide strong support for the optimization and sustainable development of the global energy structure。

Future，Sany Hydrogen Energy will continue to increase R & D investment，Deepen technological innovation，Steadfastly implement the quality-first strategy，To contribute to the high-quality development of the hydrogen energy industry, Sany Power and Sany Plan。
