With soaring oil prices and diminishing fossil fuel reserves, the development of new ways to generate electricity has become a priority. One such technology is Solid Oxide Fuel Cells (SOFC), whose elevated operating temperatures allow them to use a wide variety of fuels. Fuel cell performance is intricately related to material properties and thus a correctly engineered microstructure will increase the efficiency of the device. In this project, the effect of grain size, crystallographic orientation, morphological anisotropy, porosity, etc., are all engineered to maximize the delivered power density of the device. Moreover,  the spatial details and spatial distribution of triple phase boundaries are tailored by implementing  a novel numerical approach that resolves the local electrochemical particle-particle interactions. Improved, non-conventional device architectures are being proposed.
