Description:
In this paper we report the synthesis of a series of new Mn/Ti containing perovskites, La 1– x Mn x Mn 1– x Ti x O 3– , for investigation of their potential for use as solid oxide fuel cell electrodes, particularly anodes. Single-phase samples could be achieved for x ≤ 0.4. Above this level, La 2 Ti 2 O 7 impurities were found. Conductivity measurements showed electronic conductivity up to a maximum of 12 S cm –1 at 850°C in air. While the samples were shown to be stable in both air and 5% H 2 /N 2 , the conductivities in the latter were significantly lower (0.4 S cm –1 ), which would be an issue for potential anode applications.
