Electrochemical behaviour of Ni-BZO and Ni-BZY cermet anodes for Protonic Ceramic Fuel Cells (PCFCs) – A comparative study

Harmonic analysis based method for linearity assessment and noise quantification in electrochemical impedance spectroscopy measurements: Theoretical formulation and experimental validation for Tafelian systems

“…This feature makes the technique suitable for a large range of applications. This explains why it has been widely used in electrochemical related fields as fuel cells [6][7][8][9][10][11][12], batteries [13][14][15][16][17][18], corrosion [19][20][21][22][23], coatings [24][25][26], electrochemical sensors [27][28] and supercapacitors [29][30][31][32]. This electrochemical technique has also been used in fields that are not traditionally related to electrochemistry as biochemical assays [33][34][35][36], oncology [37][38][39] and immunology [40][41], amongst others.…”

The effect of nickel doping on the microstructure and conductivity of Ca(Ti,Al)O3–δ for solid oxide fuel cells

“…= ~10 −9 F cm −2 ) regions. 21,23 Conversely, in the spectrum obtained at 600°C, the first arc corresponds to the grain boundary response, while the second arc at lower frequencies corresponds to the electrode processes (C electrodes ~10 −6 F cm −2 ). 21,24 The impedance spectra were analyzed with two or three parallel RQ terms in series, each of them representing one of the mentioned processes.…”

Ceramic Conductors

“…Patterns of SDC thin films (JCPSD No. 01-075-0157) have peaks belonging to ( 111), ( 200), ( 220), (311), (222), and (400) crystallographic orientations (Figure 1a-c). The positions of the peaks correspond to the fluorite structure, Fm3m space group.…”

“…X-ray diffraction patterns of SDC thin films deposited 6.2 m 2 /g by evaporating powder had peaks corresponding to ( 111), ( 200), ( 220), ( 311), (222), and (400) crystallographic orientations. The X-ray diffraction patterns of SDC thin films deposited by evaporating powder (11.3 m 2 /g) had peaks which corresponded to ( 111), ( 220), (311), and (222) crystallographic orientations. ( 200) and ( 400) crystallographic orientations disappeared.…”
