Geometrical modeling of the triple-phase-boundary in solid oxide fuel cells

Journal of Power Sources, 2005
A geometrical model was developed to predict the influences of solid grain size, pore size and porosity on the triple-phase-boundary (TPB) length in electronic composite electrodes of solid oxide fuel cells. It shows that the TPB length is inversely proportional to grain size and can be optimized by the pore size and porosity.

On the accuracy of triple phase boundary lengths calculated from tomographic image data

Journal of Power Sources, 2014
Abstract The triple phase boundary (TPB) length is one of the most important quantities obtainable from three dimensional reconstructions of solid oxide fuel cells that utilize porous composite electrodes. However, the choice of TPB calculation method and the voxelation of the microstructures can lead to systematic errors in TPB estimates.

ReaxFF Reactive Force-Field Modeling of the Triple-Phase Boundary in a Solid Oxide Fuel Cell

Journal of Physical Chemistry Letters, 2014
In our study, the Ni/YSZ ReaxFF reactive force field was developed by combining the YSZ and Ni/C/H descriptions. ReaxFF reactive molecular dynamics (RMD) were applied to model chemical reactions, diffusion, and other physicochemical processes at the fuel/Ni/YSZ interface.
