Ni1 − xCux–SDC anodes for intermediate temperature solid oxide fuel cell

Abstract

Ni1−xCux bimetallic-based composite anodes were investigated for intermediate temperature solid oxide fuel cells. Ni1−xCuxO and SDC were synthesized using a glycine nitrate process. The electrical conductivity of the Ni0.90Cu0.10 is higher than Ni. The electrical conductivities of the Ni1−xCux–SDC increase with increasing Cu content (from x=0 to x=0.10) and then decrease at x=0.15. Addition of appropriate amounts of Cu into Ni–SDC to form Ni1−xCux–SDC anodes obvious improves the electrochemical performance of solid oxide fuel cells.
