Practical Design and Stacking Arrangements for the SOFC

3 Practical design and stacking arrangements for the SOFC Tubular design 

The tubular SOFC was pioneered by the US Westinghouse Electtic Corporation (now Siemens Westinghouse Power Corporation or SWPC) in the late 1970s. The original design used a porous calcia-stabilised zirconia support tube, 1 to 2 mm thick onto which the 

Several other organisations, notably Mitsubishi Heavy Industries and TOTO in Japan and also Adelan Ltd in the United Kingdom have been developing tubular SOFC designs.

Despite their fundamental attraction in terms of power density and efficiency compared with tubnlar designs, several organisations have abandoned development of the planar SOFC design because of all the inherent technical problems. These have included Siemens in Europe who had built 20-kW stacks by 1999. However, planar technology is being
