Properties of SPES/AIOOH Composite Proton Exchange Membranes
摘要
Abstract
Novel sulfonated polyether suffone (SPES)/AIOOH organic/inorganic composite membranes were prepared by doping SPES with AIOOH, which lowered the methanol crossover and increased the proton conductivity at high temperatures. The structure and performance of the obtained membranes were characterized by Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) etc. Compared with the pure SPES membrane the composite membranes had higher thermal stability and water uptake. The morphology of the composite membranes indicated that AIOOH was uniformly distributed throughout the SPES matrix. The network-like structure began to form when the AIOOH content was around 10%. The proton conductivity was still ca 0.014 S·cm-1 even at a temperature as high as 120 ℃. Additionally, the methanol resistance improved greatly as the content of AIOOH increased. The SPES/AIOOH composite membrane is a promising candidate for direct methanol fuel cell (DMFC) applications.关键词
