Solid oxide fuel cell is an efficient and environmentally friendly energy conversion technology, its commercial application has been the goal pursued by researchers. However, due to the high cost, commercial applications have not yet been realized. China University of Geosciences (Wuhan) College of Materials and Chemistry Associate Professor Wu Wu Hubei University Professor Zhu Bin and other cooperation, the successful development of low-cost new energy battery material - limonite, natural minerals in advanced energy applications provides a New way. According to media reports on March 10, the research results recently published in the field of international functional materials, a well-known academic journal "Advanced Functional Materials." This study found that in natural limonite, quartz and limestone minerals coexist, and the limonite / quartz and limestone natural complexes produce mobile oxygen and proton channels in hydrogen and air atmosphere and propose new Ion conduction and functional mechanism. Solid oxide fuel cell is an efficient and environmentally friendly energy conversion technology, its commercial application has been the goal pursued by researchers. However, due to the high cost, commercial applications have not yet been realized. Wu Yan and Zhu Bin conducted extensive screening and intensive studies on natural minerals, discovered and developed the high-grade Laiwu limonite and obtained the performance comparable to that of synthetic battery materials. As a new energy battery materials, can be used for distributed power plants, emergency power supply, transportation power supply. Wu Yan introduced, as a new type of solid battery materials, limonite in the cost, performance advantages. The current market price of 80 US dollars per ton, while the traditional solid oxide fuel zirconium dioxide market price of about 100 US dollars per kilogram. At the same time, limonite as a new type of electrolyte material, the assembled solid oxide fuel cell has a higher power output.
