Abstract: 

Electrode processes occurring in a tubular solid oxide fuel cell were studied using the distribution of relaxation time (DRT) method. The conclusion about the localization of the processes and their nature was made by analyzing the capacitances of the processes and changing their activation energy because of sequential activation of the electrodes. The greatest contribution to the total resistance of the cell was made by cathodic processes at the electrode-contact and electrode-electrolyte boundaries.
