The well-known journal "Science" published an academic paper from the research team of China University of Geosciences (Wuhan) on the 10th, announcing that through the electronic state characteristics of semiconductor heterogeneous interfaces, protons are limited to heterogeneous interfaces, and proton channels with low migration barriers are designed and constructed.
This is what the reporter learned from China University of Geosciences (Wuhan) on the 10th. Associate Professor Wu Yan of the School of Materials and Chemistry is the first author of the thesis. According to her introduction, the clean, efficient and pollution-free characteristics of fuel cells are getting more and more attention. Fuel cell technology is also a key area of ​​the national energy development strategy. The development of electrolytes with high ion conductivity is the key to solving the current fuel cell applications.
China University of Geosciences (Wuhan) fuel cell innovation research team has been committed to low-temperature, high-performance fuel cell research, focusing on the development of high-proton conductivity electrolytes, after years of exploration, after repeated experiments and demonstrations, through the semiconductor heterogeneous interface electronic state characteristics, Localize protons at heterogeneous interfaces, and design and construct proton channels with low migration barriers.
"Our research is like building a highway for protons, that is, using a semiconductor heterointerface field to induce metal states, and promoting superprotons to'run up' quickly and well, thereby obtaining excellent conductivity." Wu Yan said, this Compared with the conductivity of traditional electrolyte materials, it has improved by three orders of magnitude, and has achieved demonstration of advanced proton ceramic fuel cells.
Semiconductor heterostructures and field-induced accelerated ion migration are challenging research topics in the field of energy science. The research results provide an innovative scientific method for proton-limited transmission, which will promote the research and development of a new generation of fuel cells and have important scientific significance and application value for the development of new energy materials and technologies.
