New results from a joint Chinese and foreign scientists finished 27th aboard the "natural" website home page headline: graphene, boron nitride and other two-dimensional materials with only tolerance proton penetration characteristics, which is expected to replace the core production of fuel cells parts "proton conducting membrane" of existing materials, fuel cells spawned revolutionary progress.
The results of the University of Science and Technology of China have Professor Wu Hengan, Wang Feng super Extraordinary research associate with the Nobel Prize winner, University of Manchester, Andre? Professor Heim university researchers and research group collaboration, relevant papers in 11 published in top international academic journal "Nature" online March 26.
A fuel cell is the fuel has chemical energy directly into electrical energy generating device, a high energy conversion efficiency, without consuming recharge time, zero-emission pollution and many other advantages. From smart phones to the aerospace, defense, fuel cells can play an active role, very broad application prospects. However, the fuel cell core member "proton conductive membrane" defects such as the presence of fuel penetration, so large-scale application is very restricted.
According to the paper co-corresponding author Professor Wu Hengan introduction, graphene is an arrangement of carbon atoms formed in accordance with the two-dimensional hexagonal honeycomb lattice single mesh material, the two-dimensional BN nanomaterials also similar with graphene hexagonal structure. Conventional wisdom holds that any gas or fluid molecules molecules, even the smallest hydrogen atoms, they can not penetrate the perfect defect-free graphene sheets. Their research indicates that protons can be more easily through graphene and boron nitride and other two-dimensional materials; if elevated temperature or adding a catalyst, significantly accelerate the penetration process. Moreover, in addition to protons, other substances can not pass through the two-dimensional graphene and boron nitride materials.
According to Wang Feng introduce ultra Extraordinary Research Associate, based on the results of this study may be used, such as graphene and boron nitride single atomic layer of the two-dimensional material as "proton conducting membrane," which will make fuel cells more efficient, safer, more environmentally friendly, slimmer, will greatly expand its applications, the application will be significantly accelerated pace. Meanwhile, the results of research will also greatly facilitate the hydrogen-related technologies.
It is reported that, after the paper was published, the "natural" website page headline the first time in the form of a report, "Nature News Viewpoint" column for the same period were focused on the results of reviews and prospects. Karnik MIT professor pointed out in the comments, the proton conducting membrane is the heart of the fuel cell, this study achieved a breakthrough has been achieved in theory, the US Department of Energy's 2020 target proton conducting membrane transport properties .
