Highly sulfur tolerant Cu-ceria anodes for SOFCs
The results of a study of the sulfur tolerance of solid oxide fuel cells (SOFCs) with composite
anodes containing Cu,, and YSZ are presented. When operating a SOFC with anodes on
fuel containing sulfur impurities in the form of at 1073 K it was found that levels up to 450
ppm had no effect on anode performance. At higher concentrations, anode deactivation was
observed and can be attributed to the reaction of the with to form.
