Application of AA'-Stacked Trilayer Hexagonal Boron Nitride for Proton Exchange Membrane Fuel Cells |
| 초록 |
Hexagonal boron nitride (h-BN) and graphene have emerged as promising materials for proton exchange membranes because of their high proton conductivity and chemical stability. However, the defects and grain boundaries generated during the growth and transfer of two-dimensional materials limit their practical applicability. Here, we report the fabrication of membrane electrode assemblies using large-area single-oriented AA′-stacked trilayer h-BN, which exhibits very few defects during the growth and transfer, as a proton exchange membrane for use in fuel cell systems. The fuel cell based on AA′-stacked 3L-BN showed H2 permeation current density as low as 2.69 mA cm−2 and open circuit voltage as high as 0.958 V; this performance is much superior to those for cells based on Nafion (3.7 mA cm−2 and 0.942 V). Furthermore, the fuel cell with the AA′-stacked 3L-BN membrane almost maintained its original performance even after 100 h of an accelerated stress test at 30% RH and 90 oC. |
