| 英文摘要 | in this paper, the preparation and characterization of porous polybenzimidazole membranes doped with phosphoric acid were reported. for the preparation of porous polybenzimidazole membranes, glucose and saccharose were selected as porogen and added into pbi resin solution before solvent casting. the prepared porous pbi membranes had high proton conductivity and high content of acid doping at room temperature with 15.7 mol h3po4 per pbi repeat unit, much higher than pure pbi membrane at the same condition. further, the performance and stability of the porous pbi membrane in high-temperature proton-exchange-membrane fuel cells was tested. it was found that the cell performance remained stable during 200 h stability test under a constant current discharge of 0.5 a cm(-2) except for the last fifty hours. the decay in the last fifty hours was ascribed to the delamination between the catalyst layer and membrane increasing the charge-transfer resistance.
