Abstract

original image

Salient spatial structures: A hierarchy of spatial bifurcations during the electro-oxidation of hydrogen on platinum in the presence of negative global coupling leads to the formation of self-organized potential walls (see picture) of more than 1 V that separate oscillating active areas from high-potential passive domains.
