It is also a clean energy that accelerates the development and utilization in the context of global carbon peak and carbon neutrality. Hydrogen has the characteristics of high combustion calorific value, which is three times that of gasoline, 3.9 times that of alcohol, and 4.5 times that of coke. The product of hydrogen combustion is water, the cleanest energy source in the world. Rich in resources, sustainable development. Proton exchange membrane electrolysis from water is a new type of hydrogen production technology, which uses the principle of water electrolysis to decompose water into hydrogen and oxygen through the proton exchange membrane. This technology has the advantages of high effi ciency, environmental protection and safety, and is widely used in the field of hydrogen energy. It can be coupled to hydrogen fuel cells to power vehicles such as cars and ships. At the same time, it can also be used in the industrial production of hydrogen demand, such as the chemical industry, electronics, semiconductor and other industries. In addition, proton exchange membrane electrolysis water hydrogen production technology can also be used for energy storage to convert electricity into hydrogen storage in case of emergency. As the key core component of proton exchange membrane water electrolysis hydrogen production device, membrane electrode plays a key role in the performance, effi ciency, life and cost of water electrolysis hydrogen production. It is generally composed of proton exchange membrane (PEM), YinYang catalytic layer (CL) and Yin-Yang porous transport layer (PTL). One of the most commonly used proton exchange membrane (PEM) for commercial electrolytic water for hydrogen production is perfluorosulfonate resin membrane (PFSA). PFSA PEM PFAS 2.

Reason for the exemption: [1] The green hydrogen industry is an important driver of economic growth and job creation in Europe As we all know, Europe is one of the first regions in the world to develop and utilize hydrogen energy, and it is also one of the regions most actively promoting the development of hydrogen energy. The European Hydrogen Strategy, released by the European Commission in July 2020, is a guiding document on the development of hydrogen energy, providing a clear vision and roadmap for the establishment of an integrated hydrogen market in Europe. Subsequently, some European countries have developed and implemented strategic documents on the development of hydrogen energy at their own level, aiming to provide a clear goal and path for their own hydrogen energy market and industry. These countries include Germany, France, the Netherlands, Spain, Portugal, Italy, and Austria , Poland et al. Europe has also made important achievements in the field of hydrogen energy industry, mainly reflected in the following aspects: Electroute cell scale: Europe is the world's largest electrolytic cell market, accounting for about 40% of the global market share. By the end of 2022, there is about 300 MW (MW) of electrolytic cell capacity in Europe, and it is expected to reach 4,000 MW (MW) by 2030. Electrolysis of water to produce green hydrogen production: Europe is the world's largest green hydrogen production region, accounting for about 50% of the global market share. By the end of 2022, Europe had produced about 100,000 tons of green hydrogen, and it is expected to reach 10 million tons by 2030. Common market for Hydrogen energy: Europe is the first region in the world to establish a common market for hydrogen energy. These projects and initiatives cover the production, storage, transportation, distribution and application of hydrogen energy, involving many countries and regions, forming some trans-national and trans-regional hydrogen energy corridors and clusters. Hydrogen application field: Europe is the world's most widely used hydrogen region, industrial refineries, chemical plants, steel plant using green hydrogen or low carbon to replace fossil fuels, fuel cell vehicles, transportation, buses, trucks, trains, electricity using hydrogen storage renewable energy electricity, and release in need, construction began to use fuel cells or hybrid heating system, agricultural farms and greenhouses began to use hydrogen as fertilizer or heating source. With the reduction of the price of renewable energy electricity, the improvement of electrolytic cell effi ciency, and the emergence of scale eff ect, green hydrogen will gradually reduce the cost and improve the competitiveness, and become one of the important means to achieve the goal of carbon neutrality in Europe. At the same time, with the unification of technical standards, the improvement of infrastructure, the improvement of social cognition and other factors, green hydrogen will gradually expand the market and increase the demand, and become one of the important driving forces for promoting economic growth and job creation in Europe. In this context, it should be a consensus to ensure the large-scale development of hydrogen production infrastructure and improve the production capacity of green hydrogen, and the key materials needed in the process of water electrolysis for hydrogen production If restricted, it will greatly aff ect the development prospects and opportunities of the European hydrogen energy industry. 2PFSA PEM (PFSA) 20 60 PFSA Nafion Asahi GlassAsahi Chemicals DowBallardSolvay PFSA PFSA PFSA /25/25MPa/200/200% (TD/MD) 180/180MPa (TD/MD/Z) 25/25/25% 140mS/cm 10 [2] Perluorosulfonic acid membrane (PFSA) is irreplaceable in electrolytic water to produce green hydrogen Proton exchange membrane for PEM electrolytic water for hydrogen production requires high proton conductivity, low gas permeability, high mechanical strength and structural strength, good thermal and chemical stability, high durability, etc. Perluorinated sulfonate proton exchange membrane (PFSA) is a porous membrane easy to operate and has good weather resistance, which has many advantages and plays an important role in water treatment. Its main uses are deion, adsorption, membrane separation, catalytic reaction, degradation of organic matter and so on. In the 1960s, DuPont developed a perfluorosulfonic acid (PFSA) membrane, or the Nafion series of products. This product can be said to be a milestone in the development history of proton exchange membrane, with its excellent chemical stability, high mechanical strength, and outstanding ionic conductivity at low temperature and high humidity, making the proton exchange membrane from the laboratory to commercialization. Following DuPont, Japan's Asahi (Asahi Glass), Asahi Chemical (Asahi Chemicals), Dow Chemical (Dow) in the United States, Ballard (Ballard) in Canada, and Solway (Solvay) in Belgium have developed perfluoronic acid membranes in diff erent structures. At present, the substitute available on the market are sulfated polyimide membrane, but compared with perfluorinated sulfonic acid resin membrane (PFSA), it is found that its mechanical properties and conductivity are inferior to perfluorinated sulfonic acid resin membrane (PFSA), which is only suitable for some working conditions of this section, so it is an incomplete substitute. At the same time, the complete substitute of perfluoroplastic resin film (PFSA) must be at least meet the tensile strength (transverse / longitudinal) 25 / 25MPa, fracture elongation (transverse / longitudinal) 200 / 200%, Young's modulus (TD / MD) 180 / 180MPa, the rate of dimensional change (TD / MD / Z) 25 / 25 / 25%, proton conductivity of 140 mS / cm. According to the classification of fluorine containing cases, proton exchange membrane mainly includes perfluorinated sulfonate proton exchange membrane, partially fluorinated proton exchange membrane, non-fluorinated proton exchange membrane, and composite proton exchange membrane. Most of them are still in the research stage, and the most widely used in the market is still the perfluorinated sulfonic acid membrane, and there is no suitable replacement product in the short term (more than 10 years). 3PFSA (PVDF) (PFS) PVDF PFS PFS 99.95% PFSA OTP OTP [3] This membrane (PFSA) has no evidence of harm Perluorosulfonic acid membrane is composed of siloxane (PVDF) and perfluorosulfonic acid (PFS). It integrates PVDF and PFS at high temperature to form an oxidative polymer membrane. After improved treatment, a polymer composite membrane with nuclear magnetic bonds and multiple aperture structures is formed. Therefore, PFS has the characteristics of being driven into the membrane body by water, oxidizing in the air, reducing the physical filtration and permeability of organic matter, especially the adsorption of macromolecular organic matter. The purity of water can reach 99.95%. In addition, the PFSA proton exchange membrane has better weather tolerance. For temperature, pH, chloride concentration, OTP, and the perfluorosulonic acid proton exchange membrane can eff ectively resist these eff ects. Finally, perfluorinated sulfonic acid proton exchange membrane also has the characteristics of anti-bacteria, the surface of the membrane is very high bacterial, can effectively reduce the amount of pollutants, so as to ensure the purity of water, and can withstand high temperature, ensure the stability of water treatment process, can maintain a long filter membrane life in the high temperature state. In general, perfluorosulfonic acid proton exchange membrane is a composite membrane with easy to operate, strong weather resistance, bacterial resistance, permeability resistance to pH and OTP changes, high water purity and long filter membrane life. It is the most commonly used proton exchange membrane for hydrogen hydrogen electrolysis. The product is only used in industrial hydrogen production sites, and does not have direct contact with the human body, and there is no relevant evidence to prove that it is harmful.
