Abstract

•A New 60%NiO/Ce0.9Zr0.1O2 (ZDC6) nanomaterial was proposed as anode of SOFCs.•These anodes were successfully fixed onto SDC disks keeping their high porosity.•Dual-chamber SOFCs with these anodes were fully characterized in pure H2.•The SOFCs exhibited good power densities of 75 mW cm−2 when operated at 650 °C.

This paper analyses the electrocatalytic performance of a 60%NiO/Ce0.9Zr0.1O2 anode under reducing atmospheres, using a symmetric cell configuration, [anode/electrolyte/anode], with Samaria doped Ceria (SDC) as electrolyte. This anode exhibited excellent performance in H2 atmosphere in comparison with conventional anode materials. A dual chamber solid oxide fuel cell with 60%NiO/Ce0.9Zr0.1O2 anode, SDC electrolyte, and Pt cathode was constructed and tested under H2 atmospheres at intermediate temperatures. Good values of power densities were obtained, indicating the good performance of 60%NiO/Ce0.9Zr0.1O2 in the operating conditions.
