Corrigendum to evaluation of electrochemical properties of LaNi_0.6Fe_0.4O_3-δ - Ce_0.9Gd_0.1O_1.95 composite as air electrode for SOFC solid state ionics, 332, 2019, 70–76 (Solid State Ionics (2019) 332 (70–76), (S0167273818308117), (10.1016/j.ssi.2018.12.023))

The presented data of impedance spectra and ASC of LaNi_0.6Fe_0.4O_3-δ (LNF) in Figs. 3(a), 4, and 7(a) were found to contain errors. The Fig. 3(a) in the original paper corresponds to data at 923 K, but the normalization by apparent surface area was incorrect. The corrected version after taking into account the correct temperature of 873 K and apparent surface area of 10 mm in diameter are given in the following revised figures. In addition, the diameter of the composite electrodes should be corrected to 6–8 mm in the experimental part. Those corrections did not lead to the necessity of changing the main conclusion of the paper. The authors would like to apologize for any inconvenience this may have caused to the readers of the paper.
