Fourth International Symposium
Engineering of Chemical Complexity
Berlin, June 7-9, 2006
Program and Organization: G. Ertl, A. S. Mikhailov, H. H. Rotermund
The aim of this meeting is to review current perspectives for design, manipulation and efficient control of self-organizing complex chemical systems, ranging from biotechnology and reactive nanostructures to macroscopic pattern formation in chemical reactors. Both experimental studies of such phenomena and their mathematical modeling will be discussed. Possible technological applications of self-organization phenomena shall be considered.

Instabilities and pattern formation during electro-oxidation of H2-CO mixtures in a
fuel cell relevant system
Abstract:
Fuel cells are promising energy conversion devices and much effort is focused on their
improvement. One problem is that the fuel gas (H2) is contaminated with CO when produced
from methane, the main H2 source. CO acts as a poison since it adsorbs on the Pt catalyst, blocks
H2 oxidation and reduces the efficiency. The coadsorption of CO also introduces feedback loops
in the reaction kinetics which render homogeneous, stationary operation conditions unstable and
promote dynamic instabilities.
We present theoretical and experimental results on instabilities and pattern formation in the H2-
CO|Pt-system and discuss strategies how the dynamic instabilities can be exploited to maximize
fuel cell performance in the presence of CO contaminations.
