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.

Das ehemals in der Sammlung des Palais Granvella in Besançon und sodann in Rubens’ Sammlung belegte Gemälde "Schiffe in ruhiger See" von Pieter Bruegel d. Ä. ist heute verschollen. Mit sehr hoher Wahrscheinlichkeit kann es mit der Darstellung des Seestücks im Vordergrund der Allegorie des Sehsinns von Jan Brueghel d. Ä. und Peter Paul Rubens identifiziert werden.
