Electrochemical impedance spectroscopy measurements made on bench-scale molten carbonate fuel cells have been used to obtain more information on the inside state of a cell thiki polarization measurements alone offer. In the frequency range I kHz to 10 mHz, the impedance response exhibited two semici...
