A New Hydrocarbon-Type Polymer Electrolyte Membrane for DMFC Application
A new hydrocarbon-type polymer electrolyte membrane has been developed as a candidate of commercially available product for DMFC application. The membrane shows lower methanol crossover and swelling in the methanol aqueous solution than perfluorosulfonic acid membrane does. As a result, MEA made from the membrane showed higher power density than that of perfluorosulfonic acid membrane at higher concentration of feed methanol solution and higher current density without tremendous flooding. Promising result of the practical durability with continuous fuel cell operation for 8000 hours was also confirmed with this membrane.
