Inorganic/organic composite membrane has been prepared from Polybenzimidazole and silici tungstic acid.The membrane were characterized using SEM,TGA,DSC,XRD ,proton conductivity consequently. The conductivity of the composited membrane contains certain ratio of inorganic/organic composite material was relatively high when compare to PBI membrane. The fuel cell performance with the composite membrane including certain mixing combination ratio with tungtosilicic acid doped with DMA was compared each other and characterized. |
