ANHYDROUS PROTON-CONDUCTING POLYMERS FOR HIGH-TEMPERATURE PEMFCs 

Most of these acid-polymer combinations from the early work exhibit proton conductivity less than 10 S/cm at room temperature. If the acid content is higher, the plastifying effect of the excessive acid leads to the formation of a soft paste, unable to be processed into membranes. A breakthrough was achieved when polybenzimidazole (PBl) was hrst proposed for preparing acid-doped membranes [21]. Since then phosphoric acid-doped PBl membranes have been successfully developed and
