Abstract

Acid-doped PBI polymer electrolyte membranes have been developed and characterized for fuel cell applications at temperatures up to 200°C. Electric conductivity as high as 0.13 S/cm is obtained at 160°C at high doping levels. The water osmotic drag coefficient of the polymer electrolyte is found to be virtually zero, which allows a fuel cell to operate with no external humidification. At operational temperatures up to 200°C, a fuel cell based on this polymer membrane exhibits promising performance.
