Tape Casting of Anode Supports for Solid Oxide Fuel Cells at Forschungszentrum Jülich



This contribution describes the development of tape casting for solid oxide fuel cells (SOFCs) anode supports starting with the characterization of the powders and ending with manufacturing of cells for stack testing. After casting the support, full cells were prepared by screen printing and sintering of the functional layers. The results of single-cell and stack tests of the novel SOFC will be discussed. The new cell showed excellent electrochemical performance in single-cell tests with more than 1.5 A/cm2 (800°C, 0.7 V). Furthermore, stack tests showed no significant difference from earlier standard cells when operated at 800°C with a current density of 0.5 A/cm2.
