| Abstract: | Polybenzimidazole(PBI) composite membranes were prepared. The introduced components included inorganic proton conductor, sulfonated polysulfone(SPSF(H)). Thermogravimetric analysis indicated that the composite membranes were thermal stable up to 400 ℃ for the PBI/ZrP/PSF system and 230 ℃ for the PBI/SPSF(H) system, respectively. Phosphoric acid doped PBI composite membranes exhibited a high conductivity at temperatures up to 200 ℃ under low humidity. Single cell tests with electrolytes of acid doped PBI composites were performed at 200 ℃ under atmospheric pressure and without humidification. The maximum power density of the cell with hydrogen or oxygen as the fuel gas is 0.34 W/cm2 for PBI/ZrP/PSF(mass ratio 80:15:5), and 0.38 W/cm2 for acid doped PBI/SPSF(0.43H), respectively. |
