Copolymerization of Ethylene, Tetrafluoroethylene, and an Olefin-Containing Fluorosulfonyl Fluoride: Synthesis of High-Proton-Conductive Membranes for Fuel-Cell Applications

摘要

Fuel cells, which are devices that convert the chemical energy stored in the fuel directly into electricity, are one of the most important technologies in the 21st century. They not only provide pollution-free clean energy, but also give high-quality and more-reliable power.[1] Of all the types known today, the technology based on proton-exchange membrane fuel cells (PEMFC) is the most attractive for various applications, especially transportation and for stationary and portable devices.[2] The most important component of the PEMFC is the membrane electrode assembly (MEA), at the heart of which is the proton-conductive membrane. The key functions of the membrane are to transport protons from the anode to the cathode of the cell and to separate the fuel and the oxidant.
