Metal supported cells (MSC) are considered as the next generation of Solid Oxide Fuel Cells due to their robustness and cost-efficiency. However, improvement of their performances for operation below 700°C is a key point, as well as their durability and their manufacturing route. Within the RAMSES EU project, materials, components and processes have been tailored for MSCs. Thus, a coated metal substrate has been optimized, fulfilling the targets of low-cost, sinterability in low-oxidizing atmosphere and oxidation resistance. A customized electrolyte powder allowed decreasing the sintering temperature of 100°C compared to a reference 8YSZ powder. A modified Ni-8YSZ anode as well as a nickelate cathode was found to reach low polarization resistances of respectively 0.37 and less than 0.20 Ωcm2 at 600°C. The progressive implementation of these materials in MSC has led to improved performances in tubular MSC. Durability over 500h and 500 thermal cycles have been successfully achieved. © The Electrochemical Society.

In the present work, the electrochemical performances and the durability of two stacks were compared, the first made by LSCF and the second by Pr 2NiO4 cathode materials. Electrochemical evaluation by polarization curves and a 600h durability test, demonstrates almost identical performance of the two stacks, though a more rigorous and long term investigation is required to fully evaluate the performance of the PRN cathode-based stack. © The Electrochemical Society.
