The reduction and oxidation (redox) durability and reforming activity of MgO–NiO–YSZ composites were examined to evaluate the suitability of MgO–NiO–YSZ composites as support materials for segmented-in-series solid oxide fuel cell (SOFC) cell stacks. The MgO–NiO–YSZ composites were compared with NiO–YSZ composites. The MgO–NiO–YSZ composites showed minimal size and structural changes during redox operations at 800 °C and a nearly equivalent reforming activity to NiO–YSZ composites at temperatures ranging from 600 °C to 800 °C in spite of their lower Ni content. MgO–NiO–YSZ composites are good candidates for the support materials in segmented-in-series (SIS)-type SOFC cell stacks.
► Characteristics of MgO–NiO–YSZ were examined for support materials in SIS-SOFC. ► MgO–NiO–YSZ showed minimal size and structural changes during redox at 800 °C. ► In spite of their low Ni content MgO–NiO–YSZ showed a high reforming activity.
