Abstract

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.
