Impedance spectroscopy analysis inspired by evolutionary programming as a diagnostic tool for SOEC and SOFC

In this work, SOFC and SOEC were examined during operation by IS measurements and the results were analyzed using ISGP. The aim of this work is to show examples of DFRT models which reflect the physical processes occurring during the operation. It is demonstrated that despite the low impedance (in the mΩ range) and the narrow available bandwidth, ISGP can provide consistent DFRT models.
