Recently, ZJFD Hydrogen Energy Materials Technology Corporation, a leading manufacturer of PTFE sealing materials in China, issued an announcement:
The company's new 20,000 square meters ALK, PEM PTFE sealing gasket and plastic pole frame production line has achieved industrial production.
"Green hydrogen" produced by electrolysis of water is considered as the final direction of hydrogen production, but at present, the cost of green hydrogen is far higher than that of fossil fuel hydrogen production, and the application scenario is difficult to cultivate, making the market demand slow to open. Therefore, reducing the cost of hydrogen production is the prerequisite for the large-scale and market-oriented development of green hydrogen industry.
At present, the two mature green hydrogen production technologies are alkaline water electrolysis (ALK) and proton exchange membrane water electrolysis (PEM), and their pain points are mainly reflected in the high cost of electricity and expensive equipment.
The completion and operation of the production line of ZJFD will further reduce the cost and transportation cost of the electrolytic cell and further reduce the price of green hydrogen.
Compared with the metal electrode frame, the fluoroplastic electrode frame can reduce the weight of the electrolytic cell by more than 60% and the cost by 30%. The design capacity of the project can meet the demand of 5GW electrolytic cell sealing products, and the annual production of sealing gasket is 300,000 pieces.
At present, the company occupies 90% of the PEM seal market and 80% of the alkaline seal market. After mass production, there is still much room for cost reduction.
ZJFD has more than 20 years of experience in the design, production and installation of ALK and PEM electrolytic water hydrogen production composite sealing gasket system and non-metallic electrode frame.
Benefiting from the rapid development of China's hydrogen energy industry, ZJFD has become one of the few enterprises in China that have laid out the key components of alkaline electrolytic cells through the early layout, emphasis on technical research and development and technological innovation, and specialized in the research and development of hydrogen energy sealing and non-metallic structural materials.
At present, ZJFD is accelerating its layout in the electrolytic water hydrogen production market:
Its products for hydrogen production from electrolytic water include sealing gasket and plastic electrode frame, which can be used in hydrogen production markets such as alkaline water electrolysis (ALK), proton exchange membrane water electrolysis (PEM), anion exchange membrane water electrolysis (AEM), etc.
The sealing products are made of polytetrafluoroethylene as the base material, with excellent high temperature and high pressure resistance and corrosion resistance;
Excellent compressibility and resilience;
Low creep and stress relaxation rate;
Outstanding insulation and sealing
At the same time, on the press, ZJFD uses the imported 10000 tons Italian SACMI press.
In terms of technology and precision, the company has constantly achieved breakthroughs. It adopts the tubular rotary cutting process, which greatly reduces the manual interference on the product, and realizes efficient and low-cost production.
The sealing gasket produced by the company can ensure the thickness tolerance of 0.05MM and the internal and external dimension tolerance of 1-2MM, which directly promotes the new electrolytic cell installation process, increases the process control, realizes standardized batch production, greatly saves the installation time, and ensures the uniformity of the electrolytic cell.
At present, ZJFD's products have been widely used in the high-temperature and high-pressure corrosion resistance fields of global ALK, PEM, oil refining, petrochemical, aerospace and military industries.
