Mixed ion and electron conductive composites for single component fuel cells: I. Effects of composition and pellet thickness

“…% LNCZO pellet, similar to pure nanocomposite electrolyte pellet. This can be interpreted by the percolation theory [26,27]; the volume of LNCZO does not reach the percolation framework. While it gradually decreases to 0.87 V with 40 wt.…”

Towards the 3D Modelling of the Effective Conductivity of Solid Oxide Fuel Cell Electrodes – Validation against experimental measurements and prediction of electrochemical performance

“…determine the Nickel paths is a thinning algorithm developed by Zhang and Suen [27], which is well established in the literature [28,29]. In the preparation of NiO/10ScSZ screen-printing inks, the anode composite powders were mixed with the basic ingredients of solvent (terpineol), dispersant (hypermer KD15) and a binder (ethyl cellulose) before homogenizing them using a triple roll mill (EXAKT 80E, Germany) [30].…”

“…After sintering, the anode films were reduced in a mixture of hydrogen (10%) and nitrogen (90%) gas which was humidified at room temperature. The reduction process was carried out at 800 o C for 2 h. (Metrohm) in a mixture of dry hydrogen (10%) and dry nitrogen (90%) gas at 700 o C [30].…”

“…Also presented in Figure 4 are the electronic conductivities of a set of synthetic structures, as computed by the ResNet model. These synthetic structures were generated with similar compositions to those fabricated by Somalu et al [30] and subsequently reconstructed. understood that in real electrodes, particles are not perfectly spherical; in contrast, the synthetic microstructures are generated using spherical particles, which undergo an expansion process and become cut spheres.…”

INFLUENCE OF SINTERING TEMPERATURE ON NiO-SDCC ANODE FOR LOW-TEMPERATURE SOLID OXIDE FUEL CELLS (LT-SOFCs)

“…3 ). The ratio of powder to ZrO 2 balls was 4:1 [21]. After milling, the mixture was oven-dried at 120°C for 12 h to evaporate the ethanol and calcined at 680°C for 1 h at a heating rate of 10°C•min -1 to obtain pure SDC with carbonate powders [18,20].…”
