Polymer electrolyte membrane with high conductivity is an indispensable need in fuel cell applications due to some major drawbacks of the commonly used polymer electrolytes. We were prepared blend polymer electrolytes by blending PDDPCSFS and SPmax-1200 polymer with different ratios and observed that the blend polymer electrolytes exhibited enhanced performances compared to their parent's compounds by forming an excellent ion-conducting channel. The blend polymers, Blend (9:1), and Blend (8:2) exhibited excellent IEC (2.09 and 2.19) meq./g, σ (93.14 and 117.50) mS/cm at 80 °C under 80% relative humidity (RH), mechanical, and chemical stability, which are higher or comparable to Nafion 117.
