Abstract

Many research studies have been focusing on the long-term stability of Ni/8YSZ cermet anodes. In this contribution we present an effective method for the recovery of anode supported cells (ASC) after degradation. The application of a short-time reverse current ended up with a significant drop in the area specific resistance (ASR) of the ASC. The recovery of the ASC was attributed to an improvement of the electrochemical polarization loss in the anode functional layer (AFL), which was reduced by 40 %. This interpretation was obtained from EIS data by a combined deconvolution with the distribution of relaxation times (DRT) and Complex Nonlinear Least Squares (CNLS) fitting approach. Measurements over time proved a permanent recovery of anode performance by reverse current treatment.
