TL;DR: In this article, the local conditions in the through-thickness of the electrodes are modeled by rigidly integrating classical electrochemistry into a three dimensional multiphysics model of an electrochemical cell.

TL;DR: A finite volume method based computational fluid dynamics model has been developed and applied for a cathode-supported planar solid oxide electrolysis cell (SOEC) operating in cross-flow configuration arrangement as discussed by the authors.

TL;DR: In this paper, the authors used a three-dimensional multiphysics model to simulate a solid oxide electrochemical cell (SOC) performing CO 2 electrolysis and determine the operating conditions and locations in the porous nickel-based electrodes where carbon deposition is expected based on local conditions (gas composition, temperature and overpotential) crossing local thermodynamic thresholds.

TL;DR: This work presents an original type of solid oxide cell stack model, which is highly computationally efficient, resulting in computations which are two orders of magnitude faster than the conventional type of stack models with all geometric details explicitly represented.

TL;DR: In this article, the homogenization modeling framework for solid oxide cell stacks is extended to identify local mechanical failures, where the fracturing within a local failing point is examined by using a localization approach, where stresses in the stack model are linked to the local stresses and the energy release rate at the crack tip of the relevant interface.
