Polymer electrolyte membrane fuel cells (PEMFCs) made several revolutionary advances in power generation system because of their environmentally friendly feature. In the PEMFC system, proton exchange membrane is one of the most important elements which have a great effect on the performance of fuel cell. Nafion, produced by Du Pont, is the most widely used membrane in fuel cell industry due to its great proton conductivity and durability. However, high cost of production and complex fabrication procedure became one of the problems of Nafion delaying the commercialization of fuel cell. In this manner, hydrocarbon aromatic polymers were studied as promising PEM candidates for fuel cell applications. In this study, we prepared a series of hydrocarbon membranes which show different properties and modified them to improve fuel cell performances. The properties were investigated via ion exchange capacities, dimensional stabilities, proton conductivities, and finally fuel cell performances. |
