AEM Water Electrolysis Hydrogen Production Technology

AEM Water Electrolysis Hydrogen Production Technology – Cheersonic

Due to key material technical barriers and manufacturing challenges, AEM water electrolysis technology is still some distance away from large-scale practical application. To this end, combined with the current research status of AEM electrolysis technology, the following prospects are proposed to promote the development and commercialization of AEM electrolysis technology:

(1) Developing AEMs with high ionic conductivity, high strength and high chemical stability is the top priority for AEM water electrolysis hydrogen production technology to break through the development bottleneck. At present, the research and development of AEMs is still in its early stages. Existing products still have problems such as ionic conductivity, chemical stability, and mechanical stability that are difficult to balance under harsh water electrolysis hydrogen production conditions, and can only provide smaller-sized products, which is difficult to meet the needs of industrial applications. Therefore, it is necessary to deeply understand the degradation mechanism of the polymer backbone and cationic groups, develop highly active cationic groups/main chain/side chain structures, and construct effective ion transport channels by regulating the connection mode between cationic groups and polymer backbones to improve the ionic conductivity and stability of AEMs.

(2) Strengthen mechanism and theoretical research. First, we should conduct in-depth research on the failure mechanism of anion exchange membranes to reveal the root causes of their degradation and life limit. By deeply understanding the failure mechanism, we can improve the stability and durability of membrane materials in a targeted manner, and improve the efficiency and reliability of electrolysis. Second, we should explore the transport behavior of water molecules and gas products in the electrolyzer and study their kinetic characteristics such as restriction and diffusion. By deeply understanding the transport mechanism of reactants and products, we can design a more efficient electrolysis system. Third, we should conduct in-depth research on the OER/HER mechanism to reveal the generation mechanism of oxygen and hydrogen during electrolysis. By studying the active centers and reaction paths of the catalyst, we can develop more efficient and economical catalysts, increase the yield of oxygen and hydrogen, and reduce energy loss. However, the current research on the failure mechanism of anion exchange membranes, water transport kinetics, OER/HER mechanism, etc. still needs to be deepened, and theoretical research based on this is very necessary, which is the key to breakthroughs in electrolysis technology.

(3) Develop high-performance electrolyzer components. In order to compete with existing electrolyzer technologies, in addition to AEMs, AEMWE also needs to make breakthroughs in materials and technologies in cathode, anode electrocatalysts, ionomers, and membrane electrode assembly integration. For OER electrocatalysts, NiFe-based catalysts have the best activity among non-transition metal elements, but there is still controversy about the active site mechanism of NiFe-based catalysts, and research on their stability and potential degradation mechanisms needs to be strengthened. For HER electrocatalysts, the best performance is still various types of PtNi and Pt/C platinum-based catalysts. Among non-platinum-based catalysts, NiMo and NiCo-based catalysts have the most development potential. Doping with heteroatoms such as nitrogen, phosphorus, and sulfur can enhance HER activity. Strengthening the research and development of bifunctional catalysts can further simplify the system, reduce costs, and enhance the competitiveness of AEMWE. It is also critical to develop ionomers with high ionic conductivity and high chemical stability. Studies have found that the impact of AEI on electrolysis performance even exceeds that of AEMs. At present, most of the research is focused on the development of AEMs and electrocatalysts. It is necessary to improve the research on the characteristics of MEA, especially the interface between the catalyst layer and the membrane, and the interface between the catalyst layer and the porous transport layer. In addition, it is necessary to improve the gas diffusion layer and bipolar plate to improve the heat and mass transfer capacity and battery efficiency; finally, efforts should be made to achieve the transition of the electrolyte from weak alkaline solution to pure water or even seawater to further reduce operating and maintenance costs.

Ultrasonic catalyst coating systems are uniquely suited for these challenging applications by creating highly uniform, repeatable, and durable coatings. From R&D to production, our non-clogging technology results in greater control of coating attributes, significant reduction in materials usage, and reduced maintenance and downtime.

Ultrasonic spraying is ideal for deposition of solar cells, fuel cells, silicon cell coatings, and is increasingly used in research and production of spraying processes. Ultrasonic Spraying Materials technology can be used to deposit uniform and extremely thin coatings on substrates of any width. Ultrasonic spraying technology enables very thin coatings with extremely high uniformity, resulting in improved electronic conversion rates and transport.
