Three-phase Boundary Lenght in Solid-Oxide Fuel Cells: A mathematical Model

Janardhanan, V. M.; Heuveline, V.; Deutschmann, O.

Abstract:

A mathematical model to calculate the volume specific three-phase boundary length in the porous composite electrodes of solid-oxide fuel cell is presented. The model is exclusively based on geometrical considerations accounting for porosity, particle diameter, particle size distribution, and solids phase distribution. Results are presented for uniform particle size distribution as well as for non-uniform particle size distribution.
