Abstract

In a high-temperature fuel cell with a solid electrolyte, the solid electrolyte (44) is mounted between metal flanges (30, 30') whose surface is at least partially coated with stabilised zirconium oxide (51, 52) or a similar gas-tight ceramic material with a crystalline structure that solidly adheres to the flanges. This coating narrows the gap between the flanges at the edge of the fuel cell and enables this narrow gap to be filled with a solder glass green foil (53) or similar soldering material that laterally seals the fuel cell in a gas-tight manner when the fuel cell is assembled. The flanges are also insulated from each other. The gas flow channels (31, 31') provided in the flanges for aggressive reaction gasses may also be coated with a thin layer (41, 41') of the same material that protects them against the reaction gasses.
