Polarization curves (a) and lifetime test (b) carried out with a novel NiCu-exsolved La0.6Sr0.4Fe0.8Co0.2O3 (LSFC) perovskite composite catalyst. These tests have been carried out at 650 °C with NiCu-LSFC coated on an Elcogen cell fed with H2 and biogas (30 vol.% of CO2). (Standard deviation was < 5 mV for each data point of the overall polarization dataset).
