Abstract
Solid Oxide Fuel Cells (SOFCs) with an alternative fuel electrode based on nickel-doped lanthanum calcium titanate (La0.43Ca0.37Ni0.06Ti0.94O3-γ, LCNT) were produced with SOFCRoll geometry. The SOFCRoll is a self-supporting cell based on a double spiral shape, where all the layers are tape cast, rolled and fired in a single step. The SOFCRoll has the advantage of the planar system, thick film manufacturing techniques, robustness of the tubular design and very high volumetric surface area. The paper presents further work on cell optimisation to improve the current collection and gas distribution within a cell structure. The design modification and co-sintering of the newly developed collector fuel electrode layers allowed the optimal use of a 12 cm2 surface area.
