A review of AC impedance modeling and validation in SOFC diagnosis
In this paper, over 150 journal papers were reviewed with respect to AC impedance modeling and validation in solid oxide fuel cell (SOFC) diagnosis. Different models based on experimental AC impedance data and their advantages and disadvantages in data interpretation were discussed. The challenges currently faced by AC impedance modeling and validation were identified and possible directions and approaches in addressing these challenges were suggested.
