abstract = {A novel route was developed to fabricate anode-supported
solid oxide fuel cells with a high throughput and low
manufacturing costs. In contrast to classical manufacturing
routes, this novel route starts with the tape casting of the
thin electrolyte followed by the tape casting of the anode
and anode support. All three layers were cast green-on-green
and finally sintered to yield a gas-tight electrolyte. By
carefully selecting the raw materials for all three layers,
it is possible to manufacture near-net-shape half-cells. The
half-cells were characterized with respect to thickness,
microstructure, bending behavior, electrolyte gas leakage,
shrinkage, electrolyte residual stresses, and mechanical
strength. Finally, the cathode was screen-printed and fired,
and the full cell characteristics were obtained in
single-cell and stack tests. Additionally, a scale-up to
cell sizes of 200 × 200 mm2 was verified. Electrolyte
and anode thickness were around 20 μm, and the support
was cast to 300–500 μm. The helium leak rates were
better than the necessary internal threshold, and the
characteristic bending strength obtained was in the range of
150–200 MPa. The single-cell tests revealed current
densities of 1.0 A cm–2 at 700 mV and 800 °C
(H2/air). A first stack test proved their stackability and
operational functionality},
