Abstract

Carbon deposition is one of the operational problems in hydrocarbon fueled solid oxide fuel cells (SOFCs). Using electrochemical impedance spectroscopy (EIS), experiments are performed to detect carbon formation on button-type cermet Ni-YSZ/YSZ/LSM SOFCs. A mass spectrometer (MS) is used to monitor the outlet gas composition, and the distribution of relaxation times (DRT) is computed to analyse the measured impedance. This work presents preliminary results obtained for H₂CH₄ mixtures at OCV and 800^oC, showing an increase in the mid-frequency range (10^-3 and 10^-2 s) for methane concentrations exceeding 10 vol%.
