“…43,44 Due to these concerns, and to confirm that experimental conditions satisfy model assumptions, conductivity was also calculated by fitting to experimental data. The fit with and without fixed ionic conductivity is discussed later in the results section.…”

“…Such mechanism can result in anomalously high effective capacitance, often referred to as a chemical (or pseudo) capacitance. The capacitance values could be as high as 0.1e1 F cm À2 [43]. A comparable value of the capacitance (2.5 F cm À2 ) is obtained (LF impedance response) for under discussion composite cathode.…”

“…The Gerischer impedance response has applied to the MIEC electrodes [39,40] and the three apparent phase boundaries of electrodes such as Pt/YSZ [41,42]. It has, also, been applied to the porous ceramic anode of SOFC [43]. According to Adler [35], two of the major kinetic processes of oxygen electrode, which are the oxygen exchange and the i n t e r n a t i o n a l j o u r n a l o f h y d r o g e n e n e r g y 3 9 ( 2 0 1 4 ) 1 9 0 3 9 e1 9 0 5 0 oxide ion diffusion, can be coupled to form a single Gerischer impedance (Z G ) response.…”

“…Esta forma tan peculiar que se relaciona con la difusión en estado sólido acoplada a una reacción química superficial que ocurre en el electrodo, en el caso que concurren a la vez los procesos de difusión a través del seno y sobre la superficie del material. Este comportamiento ha sido descrito por Adler [84] para cátodos de SOFC y otros autores para ánodos SOFC [85,86] , y su espectro de impedancia se puede modelar mediante un elemento Gerischer [87] puesto que ambos son matemáticamente isomorfos. La fórmula matemática del elemento Gerischer se describe en la Ecuación 4.6:…”

“…Se están desarrollando también módulos SOFC para otra aplicación interesante actuando como unidades auxiliares de potencia (auxiliary power units -APUs -en inglés) para camiones, como los desarrollados por Delphi [86] , BMW [87,88] y Topsø Fuel Cells [89] .…”
