The membrane is characterized by FT-IR, SEM and TGA/DSC. Water uptake, oxidative resistance, ionic conductivity and methanol permeability are measured to evaluate its performance in a direct methanol fuel cell. The on-set degradation temperature of the SPSDR is above 120°C. The membranes were confirmed to retain 1–5% water vapor at 80–140 °C in the air due to the hydrophily of highly sulfonated polystyrene. The ionic conductivity and permeability of the membrane to methanol was found to increase with temperature without extra humidity supply.A direct methanol fuel cell was designed and assembled with the suggested SPSDR-PE membrane. The effect of some experimental factors such as temperature, methanol concentration, and flow rate as well as NaOH concentration on the electrical performances of fuel cells was studied and optimized.
