Abstract

Solid oxide fuel cells (SOFCs) are promising devices for stationary and portable power and heat generation, because they can use complex fuels such as hydro-carbons, CO, and alcohols. Extreme, non-equilibrium conditions and high tem-peratures (≥ 700 ˚C) required for SOFC operation hamper efforts to understand the mechanisms of component degradation in SOFCs. This talk focuses on new insights into SOFC chemistry and the conversion of carbon-containing fuels (both hydrocarbons and oxygenated) into electricity, carbon dioxide and water, gleaned from a combination of techniques including electrochemical impedance spectroscopy, voltammetry, and vibrational Raman scattering.

Dr. Rob Walker is Professor of Chemistry and Biochemistry at MSU and the Program Director for Montana’s collaborative Materials Science Ph.D. Program. His research focuses on: 1) structure, organization and reactivity at liquid interfaces and 2) high-temperature surface chemistry on electrocatalytic and metal oxide surfaces. His awards include NSF CAREER, a Sloan Research Fellowship, and Fellowship in the AAAS. With a B.A. from Dartmouth and a Ph.D. from the University of Wisconsin-Madison—both in chemistry—Rob spent 11 years on the faculty at the University of Maryland before moving to Bozeman in 2009.
