Abstract

Direct Methanol Fuel Cells (DMFC) typically operate using Nafion-based Membrane Electrode Assemblies (MEAs) up to 100C. Above this temperature, Nafion begins to degrade, hindering performance. Because temperature improves fuel cell performance PBI-based MEAs were investigated for an intermediate range temperature DMFCs. Nafion MEA performance curves confirmed the relationship between temperature and performance. However, polarization plots for PBI MEAs could not be generated. Despite this, PBI exhibited a sustained current density of 900 mA/cm2 at 0.10 V using hydrogen.
