Abstract: A cassette for a high-temperature fuel cell stack, comprising at least one fuel cell including an anode, a cathode, and an electrolyte, and a metal cell frame which surrounds the fuel cell peripherally, wherein the metal cell frame has two sections, these being an inner thin compensating frame that contacts the fuel cell and a thicker, rigid outer frame which is provided for contacting the interconnector. The inner compensating frame comprises a peripheral bead at room temperature, which entirely disappears at temperatures between 980° C. and 1100° C., as a result of the prevailing stresses. The bead has special relief functions. It is significant that this special function of the formed bead is exclusively achieved by way of the warping in the compensating metal sheet or the compensating film, and is formed solely by way of the joining sequence applied, which is to say only in combination with the joining process employed. In contrast, a component that already has a bead prior to the joining process would also be able to compensate for stresses, but not to the same extent as a bead produced using this joining process.
