Prof. Wu Heng'an and Prof. Wang Fengchao, Associate Professor of the University of Science and Technology of China, cooperated with the Nobel Prize in physics, Professor Andre Heim of the University of Manchester in the United Kingdom, and researchers from the University of Neymegen in the Netherlands, for the loss of graphene membrane materials. We have made breakthroughs in the study of transport properties and found that two-dimensional nanomaterials with single atomic layer thickness such as graphene and boron nitride can be used as good "proton conducting membranes." The international academic journal "Nature" recently published the research results online.
A fuel cell is a power generation device that directly converts the chemical energy of a fuel into electrical energy. The proton-conducting membrane, the core component of the fuel cell, has problems such as fuel infiltration, which greatly limits the large-scale application of the fuel cell.
According to Professor Wu Heng'an, co-corresponding author of the paper, the traditional view is that any gas or fluid molecule, even the smallest hydrogen atom, cannot penetrate flawless perfect graphene sheets; this study shows that protons can be more Easy to cross two-dimensional materials such as graphene and boron nitride, while other materials are difficult to cross, thus solving the problem of fuel infiltration.
“This discovery is expected to bring about revolutionary changes in the fuel cell and hydrogen-related technologies.†Wang Fengchao said that based on this research result, single-atomic-layer two-dimensional materials such as graphene and boron nitride are used as “proton conducting membranesâ€. This will make modern fuel cells more efficient, safer, more environmentally friendly, and lighter. (Reporter Yan Huimin)
