Abstract
A solid oxide fuel cell for oxidation of hydrogen, coal gas or methane, and comprising a solid oxide electrolyte which is preferably formed by YSZ, and where a thin layer of anode material is attached to the electrolyte, and where a fluid flow-controlling coupling layer furthermore is placed on both the anode and the cathode side. The fluid flow-controlling coupling layer is according to the invention formed by a number of mutually separated columns 13. Such a embodiment of the coupling layer ensures a material saving. Furthermore, the height of each cell can be reduced and thereby increase the power density.
