Solid Oxide Fuel Cells (SOFC's) are complex electrochemical devices whose designs require consideration of mass transport, electronic and ionic conductivity, and thermal management. Traditional SOFC fabrication techniques produce electrodes whose random pore geometries are not necessarily ideal with respect to the cell's functional requirements. This paper details initial experimentation involving novel multi-material direct-write printing techniques whose aim is to produce anode and cathode layers in which pore size and shape have been tailored to improve cell performance. Optical and electron microscopy are used to characterize the direct-write printed porous electrodes.
