Electrochemical performance of plasma sprayed Cu-Co-SDC mono-layer and Cu-Co-SDC/Cu-YSZ bi-layered anodes manufactured from coarse and fine feedstock powders

► Mono-layer and bi-layer Cu based anodes were manufactured by plasma spraying. ► Feedstock powder particle size did not have a large effect on anode performance. ► Anode performance degraded with time due to Cu sintering. ► Stabilization of the performance after 10-15 h was observed. ► Bi-layered anode structure only modestly improved the anode polarization resistance.
