Properties and electrochemical performance of La0.75Sr0.25Cr0.5Mn0.5O3−δ-La0.2Ce0.8O2−δ composite anodes for solid oxide fuel cells

► LSCM-LDC composite anodes were synthesized by a modified sol-gel combustion route. ► Carbon deposition rate increased with an increase in LDC amounts. ► The 50 wt.% LSCM-50 wt.% LDC composition showed the best electrochemical performance.
