High temperature fuel cell with stabilized cermet structure

High temperature fuel cell with a fuel side and an anode layer (1a) including a carrier structure (1) for a thin gas tight sintered solid electrolyte layer (2), which includes a heterogeneous phase (1b) and a hollow space formed via this phase, in the form of macro- and micropores, where the heterogeneous phase contains two partial phases, one consisting of a ceramic material and the other a metal, and the particle size of the ceramic particles is greater than 5 to less than 1 micron. An independent claim is included for preparation of the fuel cell by, for example, film pressing, roll pressing, wet pressing, isostatic pressing.
