چکیده انگلیسی
The Area Specific Resistance (ASR) of an in-situ composite cathode comprised of 50 wt% of SBSCO and 50 wt% of CGO91 (SBSCO:50) is 0.031 Ω cm2 in the first stage of measurement at 700 °C; this value of ASR increases to 0.138 Ω cm2 after 1000 h. The ASR of SBSCO:50 (in-situ sample at 750 °C) is 0.014 Ω cm2 at the initial stage of measurement; the increase of ASR after 1000 h at 750 °C is only 0.067 Ω cm2. These results suggest that the optimum temperature for in-situ firing of an SBSCO:50 cathode sample of MS-SOFC is higher than 700 °C, ideally around 750 °C.
