Zusammenfassung:A high temperature fuel cell and a method for producing the same include at least one interconnecting conducting plate which is associated with at least one electrode. A contact layer is disposed between the interconnecting conducting plate and the electrode. The contact layer is produced from an oxide mixed crystal powder which has a spinel structure and also contains, in addition to chromium, a divalent element selected from the group Ti, V, Mn, Fe, Co and Cu. The contact layer has high thermodynamic stability in addition to sufficient electrical conductivity. A high temperature fuel cell stack includes a number of the high temperature fuel cells.
