Thread Content

Chemical equipment has developed greatly in the past ten years. Praise for China's prosperity and strength in the prosperous age. It will be more lively and exciting with everyone's participation. You are welcome to participate in the forum for more exchanges and discussions. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * PEM water electrolysis (proton exchange membrane electrolysis of water) is one of the three mainstream water electrolysis hydrogen production technologies at present. It uses a proton exchange membrane to decompose water into hydrogen and oxygen, and uses chemical reactions and electrochemical reactions to generate hydrogen. Compared with traditional alkaline water electrolysis technology, PEM hydrogen production equipment has the advantages of small size, fast response speed, cleanness and environmental protection. The biggest technical challenge faced by PEM hydrogen production equipment is the core equipment - the electrolyser, which relies on scarce precious metal materials - iridium, platinum, etc. However, because it relies on the precious metal iridium, which is more expensive than platinum, as a catalyst, cost issues have always plagued the development of this technical route. On April 15, Jiageng Innovation Laboratory held a technology product launch conference and officially released a new independently developed high-performance megawatt-class PEM hydrogen production equipment product. This equipment achieves the highest performance indicators with low precious metal loading, significantly reduces the cost of hydrogen production, and takes PEM hydrogen production technology one step closer to industrialization. The product has a maximum equipment power of 1.44MW, a current density of 2.5A/cm2 at rated power, a DC power consumption of 4.3kWh/Nm3, and a DC power consumption of 3.87kWh/Nm3 at 1A/cm2. It has the characteristics of high safety, low cost, etc. It is at the leading level in the industry, and the localization rate of equipment materials exceeds 90%. The precious metal load is reduced by two-thirds, the current density is more than doubled, and greater hydrogen production per unit area of ​​the material is achieved... This is another major milestone achieved by the Jiageng Innovation Laboratory in the field of PEM hydrogen production equipment after the high-performance 100-kilowatt PEM hydrogen production equipment successfully passed the expert project scientific and technological achievements evaluation meeting on March 14, and was evaluated as "the overall level is leading in the country, and some key performance indicators have reached the international advanced level." High performance and megawatt-level advantages enable our equipment to successfully enter the energy industry. At present, the equipment has been applied and tested in various scenarios such as kilns and off-grid hydrogen production systems. The megawatt-level PEM hydrogen production system products developed on this basis are also being prepared for application testing. The team continues to break through key material science and technology problems in the fields of catalysts and membrane electrodes, and gradually completes the development and manufacturing of PEM hydrogen production systems of different sizes. The relevant results have reached the forefront of the hydrogen energy track and will play an important role in transportation, chemical industry, steel, energy storage and other fields in the future.
