Abstract: The plant with high temperature fuel cells includes a multi component sleeve for a cell stack. Axially directed chambers for an afterburning process are arranged between the periphery of the stack and an outer region of the sleeve. A construction which fixes the chambers includes a corset-like cage, the cross-section of which perpendicular to the stack axis has essentially the shape of a regular polygon. An afterburning chamber is associated with each corner of this polygon. Radial spring forces respectively act from the corners onto the associated chamber and thereby press sealing edges of the chamber onto sealing strips between chamber and stack. The sealing edges form a closed edge of a trough-like space. The trough-like space is connected via a narrow passage with an axial collection passage for exhaust gas. This collecting passage is arranged between the trough-like space and the corner.

Abstract: The plant (1) with high temperature fuel cells (11) includes a multi component sleeve (4, 12, 13) for a cell stack (5). Axially directed chambers (7) for an afterburning process are arranged between the periphery of the stack (5) and an outer region of the sleeve. A construction which fixes the chambers includes a corset-like cage (40), the cross-section of which perpendicular to the stack axis has essentially the shape of a regular polygon. An afterburning chamber is associated with each corner of this polygon. Radial spring forces respectively act from the corners onto the associated chamber and thereby press sealing edges (75) of the chamber onto sealing strips (75?) between chamber and stack. The sealing edges form a closed edge of a trough-like space. The trough-like space is connected via a narrow passage (73) with an axial collection passage (72) for exhaust gas (30). This collecting passage is arranged between the trough-like space and the corner.

Abstract: The method for the reformation of fuels, in particular of heating oil (20?) and of another liquid fuel is carried out using an oxygen containing gas (5a, 5b, 21?, 22?). The method includes the following steps: formation of a fuel/gas mixture by dispersing of the fuel in a jet of the oxygen containing gas (21?); additionally an admixture of gas of a return flow (3b) and vaporization of the dispersed fuel; generation of synthesized gas from the gas mixture by means of partial oxidation and also reformation processes by heterogeneous catalysis; branching off of the produced synthesized gas into a product flow (3a) and the return flow (3b) for a recirculation; and a regulated extraction of heat from the return flow for the setting of a predetermined temperature of a catalyst support (10) on which the heterogeneous catalysis takes place.
