Fig. 3: Performance evaluation of predicted materials.

a Distribution of rankings for all predicted performances. The three axes represent the Rp values at three different temperatures (650, 700 and 750 oC). b Distribution of rankings for the predicted performances of all experimentally validated perovskites. Blue points indicate the top 40 ranked points (excluding 9 points with high Ce content). For Fig. 3 a and b, red points represent the three materials with the best experimentally validated performance. Purple points correspond to materials with poor Rp-700 but good Rp-650 and Rp-750 in the top ranking. The Rp values for the blue points were scaled down to 1:1000 for better visualization. c Typical EIS of symmetrical cells with an anode|LSGM|anode configuration in dry air at 600 and 700 oC. d Temperature dependence of the area-specific resistance (ASR or Rp) of symmetrical cells with various air electrodes. e Distribution of relaxation time (DRT) of various air electrodes at 600 °C under a PO2 of 0.21 atm. f Summary of n values derived from frequency-dependent Rp vs. PO2 plots. g EIS of symmetrical cells with an anode|BZCYYb|anode configuration in 3% wet air at 650 oC. h j–V–P curves of single cells with various air electrodes, measured at 650 oC with a configuration of Ni-BZCYYb|BZCYYb|Cathode.
