A solution to face the NiO dissolution problem in a molten carbonate fuel cell (MCFC) is hereafter proposed. In particular the performances of a cell in which a matrix layer has been replaced by a ferrite layer are discussed. Process gas analyses, internal resistance, open circuit voltage and V-I plots at constant gas flow and composition are the data collected to assess this technical solution in cell operating conditions. In addition indications on pre and post-tests analyses are presented in order to underline the most important parameters to verify raw material suitability and the ferrite effectiveness on cathode dissolution.
