Polarization and ASR curves at 800 °C for the modified perovskite-based cells fed with H2 using three supporting electrolyte based Solid Oxide Fuel Cells (SOFCs) (e.g., CGO, LSGM, and BYCO) and a commercial Elcogen cell coated at the anode with an exsolved perovskite pre-layer. (a) Cell potential and power densities vs. current density; (b) area specific resistance vs. current density. (Standard deviation was < 7 mV for each data point of the overall polarization dataset).
