CTOnews.com November 27 news, CTOnews.com learned from the Taiyuan Iron and Steel Media Center that for the fuel cell field, Taiyuan Iron and Steel (Group) Co., Ltd. developed ultra-pure Ferritic TFC22-X connector materials for the first time and achieved batch supply, filling the domestic gap and solving the problem of "choking" of key strategic materials in the fuel cell industry.

Fuel cell is one of the most rapidly developing new energy technologies in recent years, which can directly convert the chemical energy of fuel into electricity with high efficiency, low carbon and environmental protection at medium and high temperature. the power generation efficiency can reach more than 60% and the co-production efficiency can reach more than 85%. It also has the advantages of flexible fuel, green low carbon, no use of precious metals, and can use natural gas, hydrogen, biomass gas, methanol and other fuels. Its high efficiency and low emissions make it an ideal choice for clean energy power generation.

Due to the late start of the fuel cell industry in China, it is still in the preliminary exploration stage, and there are still many problems to be solved in the development of industrialization, among which the fuel cell stack connector material is the most critical strategic material.

In order to solve the problem of "sticking neck" of the key strategic material, the production, marketing and research team of TISCO worked together to break through the key technical bottleneck of accurate control of the content of special elements without any technology and experience for reference. solve the metallurgical problems of high and special stainless steel; develop a series of deformation system, heating and cooling technology for toughness control to realize the stable production of high and special high chromium Ferritic stainless steel. Solve the technical problems of heat treatment and pickling of series products, ensure stable control of product performance and surface quality, and realize the quality control and stable production of high special and high chromium ultra-pure Ferritic stainless steel series. The successful research and development of TFC22-X super Ferritic stainless steel for fuel cell connectors fills the domestic gap and injects a strong driving force for the development of strategic emerging industries in China.
