Barnett Research Group
Northwestern University

Our group focuses on energy and advanced technology applications through the investigation of solid oxide fuel cells and transparent oxide semiconducting thin films.  In each case, the materials are created in-house via colloidal deposition, sputter deposition, and other ceramic processing techniques.

Solid Oxide Fuel Cells:

Solid-oxide fuel cells can provide pollution-free, efficient electricity generation. Our thin-film approach allows cell operation at much lower temperatures than do conventional bulk devices. We are studying the effects of electrode structure and composition on electrochemical fuel and oxygen reactions by use of different processing techniques, electrochemical modeling, and quantitative three-dimensional structural analysis.  Work is also focused on new anode materials for use with hydrocarbon fuels such as natural gas and propane.  Electrode degradation via coarsening of Ni in anodes and structural and chemical changes in LSM-YSZ cathodes is also being studied.
