A hydrated perfluorosulfonic polymer such as Nafion® operates in a limited temperature range (＜100°C). Hence, much effort has gone into the development of low-cost, high performance and temperature-resistant alternative polymer electrolyte membranes.Among various approaches, membranes based on the polybenzimidazole (PBI) and poly(2,5-benzimidazole) (ABPBI) doped with phosphoric acid have emerged as a promising candidate for high temperature PEMFC.To investigate ABPBI with acid uptake, we characterized properties of ABPBI by thermogravimetric analyzer(TGA), instron and frequency response analyzer (FRA) and so on. |
