Abstract: BaCe0.8Pr0.2O3 (BCP20) and BaCe0.6Pr0.4O3 (BCP40) powders are successfully synthesized through the Pechini method and used as the cathode materials for proton-conducting solid state oxide fuel cells (SOFCs). The prepared cells consisting of the structure of a BaZr0.1Ce0.7Y0.2O3-δ (BZCY7)-NiO anode substrate, a BZCY7 anode functional layer, a BZCY7 electrolyte membrane, and a cathode layer, are measured from 600 to 700 °C with humidified hydrogen (∼3% H2O) as the fuel and static air as the oxidant. The electricity results show that the cell with BCP40 cathode has a higher power density, which could obtain an open-circuit potential of 0.99 V and a maximum power density of 378 mW cm-2 at 700 °C. The polarization resistance measured at the open-circuit condition of BCP40 is only 0.16 Ω cm2 at 700 °C, which was less than BCP20. [ABSTRACT FROM AUTHOR]
