Abstract
© The Author(s) 2016. A physics-based model is presented to simulate the electrochemical behavior of mixed ion and electron conducting (MIEC) cathodes for intermediate-temperature solid oxide fuel cells. Analytic solutions for both transient and impedance models based on a finite length cylinder are derived. These solutions are compared to their infinite length counterparts. The impedance solution is also compared to experimental electrochemical impedance spectroscopy data obtained from both a traditional well-established La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3-$δ$ (LSCF) cathode and a new SrCo 0.9 Nb 0.1 O 3-$δ$ (SCN) porous cathode. The impedance simulations agree well with the experimental values, demonstrating that the new models can be used to extract electro-kinetic parameters of MIEC SOFC cathodes.
