摘要: 研制了聚苯并咪唑(PBI)的复合膜,复合膜中引入的组分包括无机质子导体磷酸氢锆(Zr(HPO₄)₂·nH₂O,ZrP)和聚砜(PSF),以及磺化的酸型聚砜(SPSF(H))。热失重分析表明,复合膜PBI/ZrP/PSF和PBI/SPSF(H)的热稳定性可分别达400和230℃。磷酸掺杂的PBI复合膜在温度高达200℃的低湿度条件下,呈现出高质子电导率。以磷酸掺杂的PBI复合膜为电解质,在200℃常压不加湿的条件下,以氢气氧气为燃料气进行了单电池测试,其最大功率密度分别为0.34 W/cm²(PBI/ZrP/PSF(质量比80:15:5))和0.38 W/cm²(PBI/SPSF(0.43H))。

Abstract: Polybenzimidazole(PBI) composite membranes were prepared.The introduced components included inorganic proton conductor,Zr(HPO₄)₂·nH₂O(ZrP) together with polysulfone(PSF) and the acid form of 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.
