Abstract: 

A new design of the interconnect for tubular solid oxide fuel cells was presented. The functions of electrical connection and mechanical/gas distribution were separated in this interconnect. The electrical connection of the elements was provided by a separate metal wire laid around the frame. The paste composition and parameters for inkjet 3D printing, as well as the sintering regime, were optimized, enabling the production of dense samples with high microhardness. This approach allows for the use of Zr0.9Y0.1O1.95 (YSZ) material, which is chemically and thermally compatible with the electrolyte, eliminating the conductivity and corrosion problems taking place in traditional interconnects.
