Polybenzimidazole films doped with phosphoric acid are being investigated as potential polymer electrolytes for use in hydrogen/air and direct methanol fuel cells. The advantages of this electrolyte include good mechanical properties, and low vapor permeability. Combined, these factors allow for the use of thin (< 0.005 cm) membranes in fuel cells without excessive adverse effects from fuel gas crossover to the cathode compartment and subsequent cathode depolarization. In this paper the authors discuss experimental data on the proton conductivity, thermal stability and gas permeability of this material.
