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].

Electrochemical Studies on Anode Supported Solid Oxide Electrolyzer Cells

Introduction Solid Oxide Fuel Cell (SOFC), usually converting hydrogen as well as hydrocarbon fuels directly into electricity, have the ability to operate as a Solid Oxide Electrolyser Cell (SOEC). In the electrolysis operation mode hydrogen is produced by electrochemical reduction of water. Due to the high operating temperature a reversible operation is possible, enabling a high efficiency. The performance and stability of state of the art SOFC cells in this reverse mode of operation is however still open. In this work experimental and modelling results of the SOFCand SOEC-operation of anode supported cells are presented.
