Abstract

Abstract: Solid oxide fuel cells (SOFCs) with graded porous cathode were fabricated via a multilayer tape casting and co-firing technique, which is a low-cost and reproducible fabrication process. The effects of pore formers on the electrochemical performance of graded cathode are studied to minimize cathodic polarization resistance. Examination of the microstructures reveals that the multilayer single cell had no delamination, observable cracks, or other large defects. The cell prepared by the co-firing process exhibits low interfacial polarization resistance and high power density at the operating temperature range of 700–800 °C. This simple fabrication technique can be used for optimization of electrode microstructures and cost-effective fabrication of high-performance SOFCs. Highlights: SOFCs are fabricated via a multilayer tape casting and co-firing technique. We examine the effects of pore formers on the performance of 3-layer LSCF cathode. The microstructures reveals that the multilayer single cell is well bonded. The cell exhibits low interfacial polarization resistance and high power density.
