Electrochemical Analysis of Reformate-Fuelled Anode Supported SOFC

By applying these methods in the present study, we achieved to separate the polarization mechanisms for anode supported single cells under reformate operation. It is, for the first time, unambiguously demonstrated that (a) only hydrogen is directly oxidized at the anode and (b) an additional, newly identified polarization process occurs at low frequencies, which is most probably linked to the coupling of gas transport and the heterogeneous reforming chemistry within the anode substrate [2].
