dc.description.abstract | Proton exchange membrane (PEM) fuel cells operating at elevated temperature, above 120 �C, will yield significant benefits but face big challenges for the development of suitable PEMs. The objectives of this research are to demonstrate the feasibility of the concept and realize [acid/ionic liquid/polymer] composite gel-type membranes as such PEMs. Novel membranes consisting of anhydrous proton solvent H3PO4, the protic ionic liquid PMIH2PO4, and polybenzimidazole (PBI) as a matrix have been prepared and characterized for PEM fuel cells intended for operation at elevated temperature (120?150 �C). Physical and electrochemical analyses have demonstrated promising characteristics of these H3PO4/PMIH2PO4/PBI membranes at elevated temperature. The proton transport mechanism in these new membranes has been investigated by Fourier transform infrared and nuclear magnetic resonance spectroscopic methods. | en_US |
