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 degrees C and a large proton conductivity exceeding 10(-3) S/cm above 100 degrees C under non-humidified (anhydrous) conditions. In the present study, the MEA cell with cormnercial Pt/C electrodes provided an electrical power generation of 0.3 mW/cm(2) under dry H-2/O-2 conditions at a cell temperature of 100 degrees C.
