Polymer Electrolyte Fuel Cells Based on Phosphoric Acid-Impregnated Poly(2,5-benzimidazole) Membranes

Preparation and characterization of membranes of poly(2,5-benzimidazole) (ABPBI) (as thin as 20 Mm) for polymer electrolyte
\nmembrane fuel cells are reported. These membranes were prepared by solution casting and then impregnated in phosphoric acid
\nbaths. Their characterization included t... View More
