The electrochemical behaviour of TiN-, TiN-AlN-, Cr- and CrN-coated 316L stainless steel in molten Li2CO3-K2CO3 and Na2CO3-K2CO3 melts in a reducing gaseous atmosphere (10% H-2-90% N-2) was studied using voltammetry and scanning electron microscopy combined with energy-dispersed X-ray analysis in the temperature range of 600-730 degrees C. To facilitate the identification of the electrochemical reactions the voltammetric behaviour of stainless steel, titanium, nickel and gold was also investigated. Voltammetric characteristics obtained at AlN-TiN coated electrodes showed no anodic reactions at potentials more negative than that of CO32-oxidation. Cr- and CrN-coated electrodes demonstrated a suppressed anodic dissolution after the first steady state voltammetric cycle. The voltammograms obtained for the other electrodes studied displayed the corresponding anodic metal-dissolution waves. TiN, AlN, Cr and CrN coatings seem to be the most promising as corrosion-resistant materials for the anodic compartments of molten carbonate fuel cells.
