| Popis: | Boron nitride, which is also known as “white graphene” may be an attractive filler for composite proton exchange membrane. Application of polymer electrolyte membranes in fuel cell as an electrolyte is gaining attention due to the requirement of clean energy. However, despite its attractive features it requires more consideration for complete commercialization. Herein we demonstrate the preparation of novel functionalized WHITE GRAPHENE (hexagonal boron nitride) and sulfonated poly ether sulfone (SPES) based polymer electrolyte membranes (PEM). Composite membranes have been characterized through thermal, mechanical, structural analysis. Membranes have been subjected to measure methanol permeability and proton conductivity at different temperatures for its use in DMFC. Composite membranes exhibit good physicochemical properties as well as high methanol crossover resistance. 0.5 wt % of FBN (SP-FBN-05) membrane is found to be adequate to get the better performance in DMFC. |
