Direct methanol fuel cell: transport properties of polymer electrolyte membrane and cell performance

摘要

Methanol and water absorption in 1100 and 1200 e.w. Nafion ~(circle R) membranes was determined by weighing P_2O_5 dried and methanol solution equilibrated membranes. Both methanol and water absorption in the 1200 e.w. membrane is about 70-74
