ABSTRACT:
A method for producing polybenzimidazole (PBI) fabrics for use as fuel cell or battery electrolytes by soaking a sulfonated or non-sulfonated PBI fabric in an acid solution, whereby the fibers of the fabric become swollen with the acid solution; and drying the fabric to remove residual water or methanol and concentrating the acid.
