제목 Characterization of SPAES/sulfonated clay composite membranes for direct methanol fuel cells
초록 Direct methanol fuel cells (DMFC) have major technical problems, such as slow methanol oxidation kinetics and high methanol crossover. To overcome these problems it has been proposed to increase the fuel cell operating temperature over 100-150℃ and to reduce the methanol permeability. Montmorillonite(MMT) which has excellent mechanical and thermal stability with low methanol permeability was used as a polymer matrix. We prepared hydrophilic sulfonated poly arylene ether sulfone(SPAES) with MMT and sulfonated montmorillonite(MMT-SO3H) by the substitution reaction of (3-Mercaptopropyl) trimethoxysilane. The MMT contents in the composite membranes were controlled to 0.52.0wt% based on SPAES.
