Embodiment Construction

[0042]One embodiment of a high-temperature fuel cell is an oxide-ceramic fuel cell (SOFC—solid oxide fuel cell). A high-temperature fuel cell module, which is shown schematically in a partially sectional representation in FIG. 1 and designated therein by 10, comprises an electrochemical functional device 12 with an anode 14, a solid electrolyte 16 and a cathode 18. The anode 14, the solid electrolyte 16 and the cathode 18 form an anode-electrolyte-cathode unit 20.

[0043]The anode 14 is arranged on an anode carrier 22. The anode carrier 22 is electrically conductive (electron conducting) and made of a porous material, so that the gaseous fuel can pass through the anode carrier 22 to the anode 14. The anode carrier 22 is a mechanical carrier for the anode 14, through which an electrical contacting of the anode 14 with, for example, a housing (not shown in the drawing) is enabled.

[0044]An electrical contact device 26 can be arranged on the anode carrier 22 at a side 24 located opposite the
