A low cost large-area solid oxide cells fabrication technology based on aqueous co-tape casting and co-sintering
Aqueous-based tape casting is a low-cost and environment friendly technology. In this paper, large-area fuel electrode-supported solid oxide cells (SOCs) were fabricated by this technology in conjunction with co-sintering process. A 10 cm × 10 cm single cell with NiO/Zr0.92Y0.08O2–δ fuel electrode,...

| Summary: | Aqueous-based tape casting is a low-cost and environment friendly technology. In this paper, large-area fuel electrode-supported solid oxide cells (SOCs) were fabricated by this technology in conjunction with co-sintering process. A 10 cm × 10 cm single cell with NiO/Zr0.92Y0.08O2–δ fuel electrode, Zr0.92Y0.08O2–δ electrolyte and La0.6Sr0.4Co0.2Fe0.8O3+δ/Ce0.9Gd0.1O2+δ air electrode has been successfully developed with improved electrode microstructure and hence the cell performance with the maximum power density of 534 mW cm–2 at 850 °C with humidified H2 as the fuel and air as the oxidant has been achieved. The optimal slurry formulations used in the fabrication of SOC were summarized for future reference purpose. |
