Impedance spectra of the fuel cell with LSCF electrodes recorded in 21% O2 in He in the spectroelectrochemical cell before polarization (open symbols, 873 K), after polarization at initially −100 mV, later 100 mV, followed by 300 mV (grey symbols, 823 K), and after additional ∼3 h polarization at 500 mV (black symbols, 823 K).
