Abstract

The base-acid hybrids were prepared on the basis of the doping ratio of benzimidazole and monododecyl phosphate acid. Through a strong interaction between the acidic phosphate group and basic site of the benzimidazole, the hybrids showed a high thermal stability up to 160°C and a large proton conductivity exceeding 10-3 S/cm above 100°C under non-humidified (anhydrous) conditions. In the present study, the MEA cell with commercial Pt/C electrodes provided an electrical power generation of 0.3 mW/cm2 under dry H2/O2 conditions at a cell temperature of 100°C.
