POLYSULFONE COMPOSED OF POLYANILINE NANOPARTICLES AS NANOCOMPOSITE PROTON EXCHANGE MEMBRANE IN MICROBIAL FUEL CELL

摘要

Proton exchange membranes play a critical role in the performance of Microbial Fuel Cells (MFCs) but their high price was always a big deal for commercialization of MFCs. In the present study, doped and undoped polyaniline nanoparticles/polysulfone nanocomposites membranes as a new type of PEM, were fabricated and applied in the MFC and their performance was compared with Nafion 117 as a traditional and expensive PEM. The obtained results show that MFC working by undoped Pani/Ps generated 78.1 mW/m~2which is higher than doped Pani/Ps system with 62.5 mW/m~2. However, Naion 117 generated the highest power than other types of membrane by 93 mW/m~2. It means that undoped Pani/Ps can compete in power generation with Nafion 117 and this is an outlook toward commercialization of MFC.
