Abstract

In order to increase the chemical stability of polybenzimidazole (PBI) membrane, a highly stable polymer, poly vinylbenzyl chloride (PVBC), was chosen as the macromolecular crosslinker, and 1H-1,2,4-triazol was adopted to prepare the crosslinked PBI-based membranes. The influence of the PVBC amount on membrane characteristic was investigated in detail. The results indicated that the crosslinked structure of the membrane effectively improved the chemical stability, and at the same time, the membrane presented good mechanical property and proton conductivity. The fuel cell performance for the membrane was tested with hydrogen and oxygen single cell without humidification at 150 oC, and the maximum power density reached 0.82 W?cm-2.
