It is shown that an electrochemically-driven oxide overcoating substantially improves the performance of metal electrodes in high-temperature electrochemical applications. As a case study, Pt thin films are overcoated with (Pr,Ce)O2−δ (PCO) by means of a cathodic electrochemical deposition process that produces nanostructured oxide layers with a high specific surface area Published in:
