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.

Abstract: A solid oxide fuel cell includes a cathode, a YSZ-electrolyte, and an anode, where the cathode is formed by a mixture of LSM and YSZ. According to the invention the content in the cathode of YSZ amounts to 20 to 75% by weight, whereby it is possible to reduce the polarisation resistance to 0,08.OMEGA.cm.sup.2 at 40 mV. Furthermore, a mechanically stable structure is obtained.
