Abstract

Sulfonated polyimide (SPI) membrane has been evaluated as an electrolyte membrane for direct methanol fuel cells (DMFCs) in comparison with Nafion®112. The membrane-electrolyte assemblies (MEAs) were made by hot-pressing each membrane, an anode of Pt–Ru dispersed on carbon black (Pt–Ru/CB) and a cathode of Pt/CB with Nafion® ionomer. The cell prepared with SPI membrane exhibited a suppressed methanol crossover to a half of Nafion®112, resulting in the improved cell performance.
