Project Type MQP Submission date 2008-04-22 Authors Denise A Gleason, CM Kristoffer Geert Jensen, CM Garima Painuly, CM URN E-project-042208-005503 Title Proton Exchange Membranes and Membrane Electrode Assemblies for Enhanced Direct Methanol Fuel Cell Performance Advisor Datta, Ravindra, CM Availability unrestricted Abstract
Direct methanol fuel cell (DMFC) performance is limited by methanol permeation through Nafion membranes and interfacial resistances between membrane electrode assembly (MEA) layers. An analysis of several membrane systems showed that Nafion impregnated with Silica nanoparticles and bilayer membranes incorporating two equivalent weights of Nafion exhibited the most favorable balance between protonic conductivity and methanol crossover at high methanol concentrations. In terms of MEA fabrication, spraying catalyst directly on the membrane achieved closest contact between the membrane and catalyst.
