Characterization and Performance of Direct Methanol Fuel Cell with Radiation-Grafted Membranes |
| 초록 |
Proton exchange membrane property is key determinants of the performance of the membrane-electrode assemblyin direct methanol fuel cell. To develop a highly chemically stable membrane for application in a DMFC, styrene monomer were graft copolymerized into fluorinated ethylene propylene (FEP) and poly(tetrafluoroethylene perfluoropropyl vinyl ether) (PEA) films followed by sulfonation. The graft copolymerization was prepared by the γ-ray radiation grafting technique. Sulfonation of the radiation-grafted films was carried out in a chlorosulfonic acid solution. The effects of the reaction parameters on the content of PS grafted in the FEP and PEA films were investigated. The chemical property of the membranes in comparison with commercialized Nafion 112 was studied by Fourier transform infrared spectroscopyand thermogravimetric analysis. The transport properties of membranes such as ionic conductivitywere evaluated. The cell performance of membranes using radiation grafted method was measured by single cell test and the cell resistance was measured by an impedance analyzer. |
