Abstract

La0.75Sr0.25Cr0.5Mn0.5O3-δ (LSCM) anodes incorporated with Ag paste (AP) sintered at a relatively low temperature of 900 °C were evaluated. The results of electrochemical impedance spectroscopy displayed that the optimal electrochemical performance was acquired by incorporating 40 wt% Ag paste into the LSCM matrix. The electrical conductivity of LSCM–40AP at 800 °C in air and H2 was 192 S cm−1 and 9.96 S cm−1, respectively. The maximum power density of the cell with LSCM–40AP at 800 °C exhibited a considerable increase by a factor of 1.6, when compared with the cell with pure LSCM. The durability of the single cell with the LSCM–40AP anode was analyzed. The result revealed that the cell voltage slightly reduced from 0.67 to 0.64 V at a constant current density of 0.25 A cm−2 after a 100 h test, indicating good long-term stability of the anode sintered at 900 °C.
