Terminally-Crosslinked Sulfonated Poly(fluorenyl ether sulfone) as a Polymer Electrolyte Membrane for both PEMFC and DMFC Application

摘要

Proton exchange membrane (PEM) is a main component of the proton exchange membrane fuel cells (PEMFCs) and direct methanol fuel cells (DMFCs) for transferring protons from anode to cathode as well as providing a barrier to the fuel gas between two electrodes. Some specific limitations for the well-known perfluorinated membranes including high cost, high methanol permeability, and loss of the preferable properties at high temperature (80 °C) demand a search for alternative PEMs."
