英文摘要 | the electrochemical properties of an sm0.5sr0.5coo3-delta/co3o (ssc/co3o4) composite cathode were investigated as a function of the cathode-firing temperature, ssc/co3o4 composition, oxygen partial pressure and co2 treatment. the results showed that the composite cathodes had an optimal microstructure at a firing temperature of about 1100 degrees c, while the optimum co3o4 content in the composite cathode was about40 wt.%. a single cell with this optimized c-40-1100 cathode exhibited a very low polarization resistance of 0.058 omega cm(2), and yielded a maximum power density of 1092 mw cm(-2) with humidified hydrogen fuel and air oxidant at 600 degrees c. the maximum power density reached 1452 mw cm(-2) when pure oxygen was used as the oxidant for a cell with a c-30-1100 cathode operating at 600 degrees c due to the enhanced open-circuit voltage and accelerated oxygen surface-exchange rate. x-ray diffraction and thermogravimetric analyses, as well as the electrochemical properties of a co2-treated cathode, also implied promising applications of such highly efficient ssc/co3o4 composite cathodes in single-chamber fuel cells with direct hydrocarbon fuels operating at temperatures below 500 degrees c.
