Abstract:
1. A plant comprising a stack of high temperature fuel cells and a multi-component sleeve surrounding the stack, the sleeve including a plurality of axially directed afterburning chambers, wherein a construction which fixes the afterburning chambers is arranged between the periphery of the stack and an outer region of the sleeve, wherein the construction includes a part, the outer wall of which forms a cage having a cross-section perpendicular to the stack axis which has essentially the shape of a regular polygon, wherein each of the plurality of afterburning chambers are arranged in respective corners of the polygon, wherein radial spring forces respectively act from the corners onto the associated afterburning chambers and thereby press sealing edges of the afterburning chambers onto sealing strips between the afterburning chambers and the stack, wherein the afterburning chambers each comprise a trough-shaped space and the sealing edges are closed edges of the trough-shaped space, wherein each trough-shaped space is connected via a respective narrow passage to a respective axial collecting passage for exhaust gas, and wherein each collecting passage is arranged between the respective trough-shaped space and the respective corner, and wherein the radial spring forces are produced by strips and springs, wherein the strips lie on the afterburning chambers, and wherein the springs are arranged in the corners.
