Spray-casting ABPBI membranes for high temperature PEM fuel cells

The preparation and characterization of membranes of poly[2,5-benzimidazole] (ABPBI) by spray casting at room temperature from an ethanol solution is described. The prepared membranes doped with 11 M H3PO4 sorbed 1.5 molecules of acid per imidazole ring exhibiting a proton conductivity of 0.05 S · c...
