Abstract

Solid oxide fuel cells (SOFCs) are the most efficient devices for the direct conversion of the chemical energy stored in fuels such as hydrogen and hydrocarbons into electricity. The development of highly efficient and robust SOFCs requires cathodes and anodes with high electrocatalytic activity for oxygen reduction and direct oxidation of hydrocarbon fuels, respectively. In this talk, I will introduce our on-going research including both experimental and modeling studies of solid oxide fuel cells.

The experimental work involves material synthesis, device fabrications, and electrochemical testing as well as various characterizations such as x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), electrochemical impedance spectroscopy, etc. I will introduce these capabilities in our laboratories. As an important complimentary, modeling technique may provide a unique approach to probe internal processes for fundamental mechanism understanding that otherwise would be difficult for experiments particularly at very aggressive operating conditions. I will also introduce our modeling capability such as modeling multi-physicochemical processes in combination with the detailed surface chemistry, simulated electrochemical impedance spectroscopy, and model based electrode optimization designs.
