Abstract

A half-cell comprising of a Ni/3YSZ support, a Ni/CGO10 active fuel electrode, a thin ScYSZ electrolyte and a CGO10 barrier layer was realized through tape casting, lamination and co-sintering. After screen printing of air electrode and contact layer, the cell was electrochemically tested using EIS at open circuit voltage. At 750°C in 50/50 H₂O/H₂ohmic resistance (R_s) was encouraging at 0.18 Ω.cm². Polarization resistance (R_p) was however significantly larger than state of the art (SoA) cells at 0.45 Ω.cm². From electrochemical analysis the causes for the large R_pare hypothesized to be poor air electrode performance and low fuel electrode performance. This transaction paper includes a description of ongoing activities to improve the electrochemical performance of this cell concept to approach or surpass SoA fuel electrode supported solid oxide cells (FE-SOC) relying on Ni/YSZ electrodes.
