Abstract

The electrooxidation reaction in the Ni/YSZ anode is still a limiting factor for the performance of anode supported SOFCs (ASC). An effective method for the improvement of anode performance is based on a short-time application of a high current density in reverse direction (reverse current treatment, RCT). In this contribution we evaluate this in-situ method for different oxygen partial pressures, current densities, durations, and the number of treatments. New information on the interplay between formation parameters and nanostructure characteristics is provided, giving new insights on nano-structuring of SOFC anodes.
