Currently, Solid Oxide Fuel Cell (SOFC) electrodes have not been explored for optimization of graded electrodes and nonlinear functional grading. In this work, a complete SOFC electrode model is adapted from literature for use in analyzing and comparing the losses between homogeneous, linearly, and nonlinearly graded electrodes. Particle size and porosity functional grading reduce diffusion losses near the electrode's free surface, while decreasing activation loss levels near the electrolyte interface. A range of particle sizes was identified, around the optimal homogenous electrode particles size, where particle size grading is beneficial. This work draws conclusions about (1) relative loss contribution in a SOFC electrode, (2) optimal performance of electrodes based on particle size and porosity grading ranges and their associated grading profiles, and (3) design criteria for the efficacy of particle size graded verses homogeneous electrodes.
