AEM Hydrogen Electrode Released! JUNA TECH Upgrades Three Major Green Hydrogen Electrodes

Research and breakthroughs in core components and materials are seen as key to overcoming homogenization and intense competition in the water electrolysis hydrogen production industry.

Against this backdrop, water electrolysis equipment and core component companies are ramping up R&D investments to accelerate breakthroughs in new catalysts, high-performance membrane materials, electrodes, and diaphragms. Among them, JUNA TECH has emerged as an industry leader, leveraging its deep technical expertise and innovation in green hydrogen electrode materials.

Recently, JUNA TECH has made another breakthrough, introducing a new generation of its three major green hydrogen electrode products. The JE Series AEM  have been officially released, while the latest test data for the JA alkaline and JP PEM have been unveiled. These core products have achieved significant technical advancements and are making solid strides in commercialization. With mass production set for 2025, they will provide strong momentum for the large-scale development of the green hydrogen industry.

JUNA TECH Launches the JE Series AEM 

On January 15, JUNA TECH held a product launch event in Chengdu, unveiling the JE Series AEM —high-activity, cost-effective solutions designed for weak alkaline environments.

The new electrode adopts CCS method, and the cathode and cathode catalysts have high catalytic activity, with performance >3.0A/cm²@2V@60℃, and 1.0A/cm²@60℃ at a small chamber operating voltage of 1.7V. Based on the special catalyst growth process, the electrode has unique advantages such as low shedding rate and customizable production, especially the anode, which has the capacity for mass production with a maximum size of 1.2m*1.2m.

JE30000 performance curve

The highlights of the new JE series products are not only high performance, but also excellent durability and adaptability. "In actual applications, the JE30000 electrode can maintain stable performance output over a long period of operation, meeting customers' needs for efficient and stable hydrogen production.

At the same time, the JE series provides a variety of substrate adaptation solutions, whether it is nickel foam of different specifications (size, PPI, surface density, etc.) or nickel felt and other substrate materials, it can achieve a good matching effect. "The person in charge of AEM electrode products of JUNA TECH pointed out.

In fact, the core team of JUNA TECH has started the research and development of AEM electrode core technology and key materials since 2022. After more than two years of hard work, it launched the JE series AEM  products at this time, accurately capturing the pulse of the market.

AEM  technology combines the advantages of alkaline and PEM , and is known as the third-generation water electrolysis hydrogen production technology. It has experienced explosive growth in the past 2024: more than ten companies have launched new products on the market, and the number of new AEM  products is basically the same as that of the first-mover routes ALK and PEM, showing strong market potential.

At the application level, AEM electrolyzers will gradually begin to be used on a small scale in 2024. Owners such as West Lake University and Shandong Hydrogen into Thousands of Homes Project will bid for small-scale AEM electrolyzers. China Southern Power Grid Energy Storage will use MW-class AEM electrolyzers, and high-power AEM will be commercialized.

At the same time, the supply chain of AEM's core hydrogen production components is also being rapidly built in response to the matching, but it inevitably presents the characteristics of "fast but unstable" and "many but not refined". Electrolyzer customers have many pain points for AEM's electrode products, such as low cost, large size, long life, and large-scale production. Currently, there are only a few companies that can meet these demands.

JUNA TECH's JE series AEM hydrogen production electrode products accurately grasp these pain points. Through electrochemical technology innovation and process optimization, they have achieved effective cost control. At the same time, they have also performed well in terms of large size and reliability. They can effectively improve the overall performance and operating efficiency of AEM electrolyzers, and promote the implementation and promotion of AEM hydrogen production technology in more application scenarios.

JA Alkaline and JP PEM  Innovations Revealed

At the press conference, JUNA TECH simultaneously displayed the latest data of its two major series of hydrogen production electrode products: JA alkaline series and JP PEM series.

Under the industrial-grade 20-square-cell test conditions, the JA10000 10,000-ampere-level high-performance alkaline solution electrode product achieved uninterrupted stable operation for up to 2,000 hours at 6,000A/m²@1.8V. This is a rare industrial electrolytic cell verification data that has been running stably for a long time under high-density conditions in the industry, further verifying the excellent stability of JA10000. In laboratory tests under simulated working conditions, the JA10000 electrode product has remained stable at 6,000A/m² for ~10,000 hours (continuous testing).

"In 2024, the JA10000 product has successfully obtained the national first major technical equipment certification, the National New Materials Testing and Evaluation Platform (Sichuan Regional Center), and Bureau Veritas Quality Technical Services (Shanghai) third-party certification, indicating that the company has made important achievements in breaking through key technical bottlenecks and realizing the industrialization of efficient hydrogen production equipment." 

JUNA TECH said: Based on the product promotion strategy of "applying one generation, developing one generation, and reserving one generation", JUNA TECH's higher density alkaline solution electrode products have completed the laboratory long-term stability verification.
