碩士 === 元智大學 === 化學工程與材料科學學系 === 99 === On this thesis, we prepare Nafion/PBI blend membranes and study their mechanical properties, proton conductivities, methanol permeateon and the application to direct methanol fuel cell (DMFC). We find the membrane with a Nafion/PBI wt ratio of 9/1 has a optimum property. The Nafion/PBI blend (9/1 g/g) with a thichness of 78 μm is used to prepare MEA and performed DMFC test. The experiment results show that the present membrane had a better DMFC performance than Nafion-117.
