Three-dimensional analysis of porous Ni-GDC (gadolinia-doped ceria) cermet for solid oxide fuel cell (SOFC) electrodes is demonstrated using focused ion beam tomography. The electrodes are fabricated through the infiltration technique, introducing nano nickel particles into the GDC ceramic framework structures. Microstructural analysis revealed that the infiltrated electrodes have one order of magnitude larger TPB density than conventional electrodes fabricated by powder mixing and sintering methods, and have a greater potential to satisfy a variety of requirement for SOFC electrodes, which is a significant advantage in developing design-optimized electrode microstructures.
