dc.description.abstract | The electrochemical characteristics of the samarium and strontium doped layered perovskite (SmBa1-xSrxCo2O5+delta), x = 0.5) have been investigated for possible application as a cathode material for ail intermediate temperature-operating solid oxide fuel cell (IT-SOFC). The cathodic polarization of single-phase and composite cathodes with 10 mol % gadolinia-doped ceria (Ce0.9Gd0.1O2-delta, CGO91) shows that a weight ratio between SmBa0.5Sr0.5Co2O5+delta (SBSCO) and CGO91 of 1:1 (50 wt % SBSCO and 50 wt% CGO91, SBSCO:50) gives the lowest area specific resistance (ASR) of 0.10 Omega cm 2 at 600 degrees C and 0.013 Omega cm(2) at 700 degrees C. The maximum and minimum electrical conductivity in SBSCO are 1280 S cm(-1) at 50 degrees C and 280 S cm(-1) at 900 degrees C, with the influence of oxygen partial pressure indicating p-type conduction. The maximum power density of SBSCO:50 in an anode supported SOFC was 1.31 W cm(-2) at 800 degrees C and 0.75 W cm(-2) at 700 degrees C. | - |
