On July 10, 2023, Chunhua Hydrogen Energy Technology (Hunan) Co., Ltd. released its self-developed high-power PEM hydrogen production and hydrogen storage application integrated system equipment in Xinma Jingu Industrial Park, Zhuzhou High-tech Zone, a state-level high-tech zone.

This is the first set of independent research and development and production of PEM production, storage and use of integrated system equipment released in China, and it is also the first set of major technical equipment in Hunan Province to apply the first batch of hydrogen production and energy storage equipment, the set of integrated system equipment includes PEM hydrogen production device, purification device, storage device and fuel cell power generation device, its independent invention technology production of high-pressure differential PEM electrolyzer can achieve direct production of 7.0MPA high differential pressure, 99.999% purity hydrogen, current density of more than 2A/cm2, The single-layer voltage does not exceed 1.9V, which can not only achieve second-level start-stop and second-level dynamic response, but also operate reliably in the power range of 5%-150%.

Chunhua Hydrogen Energy Technology (Hunan) Co., Ltd. is the first PEM water electrolysis hydrogen production industrialization company established in Hunan by the founding team of Chunhua Hydrogen Energy Technology Co., Ltd., and is a hydrogen energy high-tech enterprise introduced by Zhuzhou New Energy Automobile Industry Chain and Zhuzhou High-tech Zone as a key investment promotion project.

The high cost has always been an important reason restricting the development of PEM electrolyzers. From 2015 to 2023, the company's founding team has accumulated a solid foundation after nearly 10 years of investment in all aspects of product research and development, testing and certification, technical reserves, intellectual property layout and market docking, and has invested more than 100 million yuan in various expenses during the period. Based on the long-term technology accumulation in the PEM water electrolysis hydrogen production industry, the company has a complete independent intellectual property rights system, authorized 7 invention patents, and the team has participated in the formulation of a number of national standards in related fields.

The company has independently developed high-efficiency membrane electrode preparation technology, cost-effective bipolar plate design technology and processing technology, high-efficiency high-pressure sealing structure technology, high-performance flow field plate design technology and PEM water electrolysis system integration and testing technology. At present, the high-efficiency membrane electrode preparation technology developed by Chunhua Hydrogen Energy has further improved the efficiency of cathode and anode catalysts. Through the design of high integration, the PEM hydrogen production system can refine the components under the condition of ensuring the excellent performance of the electrolyzer, which can be completely localized and break through the blockade of foreign technology. Combined with the characteristics of low power consumption and high residual value of PEM electrolyzers, the company has always adhered to the development and application of megawatt-level electrolyzers and the technical iteration of small and medium-sized electrolyzers, and continuously improved the materials, structures and process systems of electrolyzers. In the future, the reliability and cost-effective advantages of PEM water electrolysis hydrogen production equipment will increase significantly.

The high-power PEM hydrogen production and energy storage application integrated system equipment displayed at the press conference has passed dozens of experimental verifications, and the overall technology has reached the international advanced level.

This set of integrated system equipment can be coupled with hydrogen production and energy storage of photovoltaic and wind energy and the power conversion output of hydrogen energy, and can also collect waste heat, provide heat energy and refrigeration, and can be widely used in multiple application scenarios such as energy storage distributed energy supply and combined heat and power, with a broad application space and market.

In the early stage of the release of Chunhua Hydrogen Energy's high-power PEM hydrogen production and energy storage application integrated system equipment, a large number of R&D, testing, verification and other work have been done, and product sales contracts have been reached with key central energy companies in China, and the customer will install and run them on site in the near future. In terms of supporting supply chain, Chunhua Hydrogen Energy has also reached in-depth cooperation with leading enterprises in the industry. This means that Chunhua Hydrogen Energy's PEM water electrolysis hydrogen production equipment of various types is about to enter the stage of standardization and mass production and sales.

The conference was highly valued by the leaders of Zhuzhou City, and the leaders of relevant departments visited the production line and participated in the unveiling ceremony, and gave high affirmation and evaluation to the work of Chunhua Hydrogen Energy in the development of hydrogen energy industry in Zhuzhou. Leaders and researchers from CRRC, Jinhong Gases, Hanergy Technology, Kerui Inverter and many other enterprises also participated in the conference.
