Rolled tubular solid oxide fuel cells are manufactured in a low-cost single step firing process, so the design offers reduced production cost. All components are produced using a low cost tape casting method and are fired as a single unit. The geometry is self–supporting which removes the need for thick cell components further reducing cell cost and offering increased volumetric power densities. Here we present the results from some early studies on the influence of fast thermal cycling on performance characteristics. Thermal cycles were carried out heating and cooling at 10 °C min−1 between 400 and 800 °C. Less than 1% performance drop was calculated for the single cell and 5% drop was observed on the fourth cycle for the five cell bundle.

Abstract A water-based tape casting slurry is reported to prepare the ceria and scandia co-doped zirconia (ScSZ) electrolyte films. The slurry is characterized and optimized through Zeta potential and rheological property measurements. Smooth and flat ScSZ electrolyte films are obtained by improving the sintering process. The microstructure, electrical performance, and mechanical property of ScSZ with adding different contents of Al2O3 are also investigated. The results show that a proper amount of Al2O3 has a beneficial effect on the densification of ScSZ. Significant decrease at the grain boundary resistance of ScSZ is observed by Al2O3 addition. The bending strength of the sample with 0.5 wt.% Al2O3 (ScSZ-0.5A) is about 400 MPa, which is 20% higher than pure ScSZ. The ScSZ-0.5A electrolyte film fabricated by water-based tape casting method shows appropriate electrical conductivity and high mechanical strength, which is promising for the practical application in solid oxide fuel cells (SOFCs).
