Composites consisting of SrTiO 3 ‐based perovskite and either yttria‐stabilized zirconia or ceria were investigated. The mechanical compatibility and possible inter‐diffusion between phases were characterized by scanning electron microscopy, X‐ray diffraction, and energy‐dispersive X‐ray spectroscopy. A gradual disappearance of Ce‐containing phases with an increase in the temperature of reduction in hydrogen was noticed. Moreover, a diffusion of Sr, Ti, and Ce was observed between the composites and the yttria‐stabilized zirconia electrolyte support in the conditions of high temperature (1300–1400 °C) reduction in H 2 .
