A Novel Design of a Planar SOFC with the Anode Supported on the Base Ceramic Structure

摘要

The paper presents the innovative design of a ceramic high temperature solid oxide fuel cell(SOFC) in which the anode consists of two parts: the bottom supportive part withmicrochannels for fuel distribution and the upper operating part which takes part in theelectrochemical reaction in the cell. Both parts of the anode are made of co-fired yttriumstabilizedzirconia (Ni/YSZ) foils. Microchannels as well as the manifold for combustionproducts are engraved mechanically in the isostatic pressed stack of Ni/YSZ foils beforetheir firing. The electrolyte and the cathode are performed on the upper functional part ofthe anode by successive screen printing and firing of the electrolyte paste and the cathodepaste. The paper reveals details of the fuel cell processing, test fixture and measurementset-up for testing the cells as well as the results of open circuit voltage and short-circuitcurrent measurements.
