Electrochemical AC impedance model of a solid oxide fuel cell and its application to diagnosis of multiple degradation modes

A finite element model of the impact of diverse degradation mechanisms on the impedance spectrum of a solid oxide fuel cell is presented as a tool for degradation mode identification. Among the degradation mechanisms that cause electrode active area loss, the attention is focused on electrode delami...
