摘要：
A numerical methodology for evaluating the three-phase boundary length in sintered composite electrode layers is developed. Three dimensional models of sintered composite electrodes are generated for which the mean particle diameter, composition, and total porosity may be specified as input parameters. Tomographic methods are used to reconstruct the modeled electrode and the percolation for each phase is evaluated. The connected three-phase boundary length is calculated for a range of electrode designs.
