YSZ-based SOFC with modified electrode/electrolyte interfaces for operating at temperature lower than 650°C

Morphology and electrochemical activity of SOFC composite cathodes: I. experimental analysis

“…This layer also acts to prevent metallic interconnect oxidation. Recently, an additional thin functional layer has been included in the electrode/electrolyte interface [9,10] to improve electrode electrochemical activity. This is often similar to the bulk electrode, but with a different grain size distribution and morphology.…”

Fabrication of (Sm, Ce)O2−δ interlayer for yttria-stabilized zirconia-based intermediate temperature solid oxide fuel cells

“…The SDC interlayer was prepared by dip-coating method [7]. Stable SDC slurry was formed by mixing SDC powders (synthesized using a citric combustion process [23]) with ethanol as solvent, triethanolamine as dispersant, polyethylene glycol and dibutyl phthalate as plasticizer and poly-vinyl-butyl as organic binder.…”

“…High operating temperatures cause many problems, such as a limited choice of connecting materials [3], thermo-mechanical degradation of the materials [4] and increased fabrication costs [5]. Various technique have been [6][7][8][9][10][11] developed to deposit thin film electrolyte to reduce the ohmic resistance and decrease the operating temperatures of SOFCs. However, the polarization losses with La 0.8 Sr 0.2 MnO 3Àd as the cathode becomes dominant at lower operating temperatures [12].…”

Three-dimensional numerical and experimental investigation of an industrial-sized SOFC fueled by diesel reformat – Part I: Creation of a base model for further carbon deposition modeling

“…(12). Here, E is the total energy per unit mass, k eff is the effective thermal conductivity (defined according to the flow regime; either laminar or turbulent), h i is the enthalpy and J i !…”
