摘要: Abstract This paper reports the characterization of a Nafion ® /bacterial cellulose (BC) nanocomposite prepared by impregnation nanofibrillar BC membrane with . Such is obtained crack-free and thickness close to 100 μm. Dynamic mechanical analysis reveals storage modulus more than 1 order magnitude higher for pure , effectively limiting viscous flow up 125 °C. The in-plane protonic conductivity 0.14 S cm −1 at 94 °C 98% relative humidity, which lower but in line concentration acid groups composite (0.60 vs. 0.92 mmol [H + ] g ). application /BC an air/hydrogen fuel cell demonstrated.
