Abstract
(DE)
Die Anlage (1 ) mit Hochtemperatur-Brennstoffzellen (11 ) umfasst eine Multikomponenten-Hülle (4, 12, 13) zu einem Zellenstapel (5). Axial ausgerichtete Kammern (7) für eine Nachverbrennung sind zwischen der Peripherie des Stapels (5) und einem äusseren Bereich der Hülle angeordnet. Eine die Kammern fixierende Konstruktion umfasst einen korsettartigen Käfig (40), dessen senkrecht zur Stapelachse liegender Querschnitt im wesentlichen die Form eines regelmässigen Vielecks hat. Jeder Ecke dieses Vielecks ist eine Nachverbrennungskammer zugeordnet. Aus den Ecken wirken radiale Federkräfte jeweils auf die zugeordnete Kammer ein. Dabei werden Dichtkanten (75) der Kammer auf Dichtungsstreifen (751) zwischen Kammer und Stapel aufgepresst. Die Dichtkanten bilden einen geschlossenen Rand eines wannenförmigen Raums. Der wannenförmige Raum ist über einen Engpass (73) mit einem axialen Sammelkanal (72) für Abgas (30) verbunden. Dieser Sammelkanal ist zwischen dem wannenförmigen Raum und der Ecke angeordnet.
(EN)
The unit (1) with high-temperature fuel cells (11) comprises a multi-component sleeve (4, 12, 13) for a cell stack (5). Axially arranged chambers (7) for a post-combustion are arranged between the periphery of the stack (5) and an external region of the sleeve. A construction fixing the chambers comprises a cage (40) in the manner of a corset, the cross-section of which perpendicular to the stack axis essentially has the form of a regular rectangle. Each corner of the rectangle is provided with a post-combustion chamber. Radial spring forces act on the corresponding chambers from the corners. Sealing edges (75) of the chamber are thus pressed against sealing strips (751) between the chamber and the stack. The sealing edges form a sealed edge of a trough-shaped chamber. The trough-shaped chamber is connected to an axial collector chamber (72) for exhaust (30) by means of a bottleneck (73). Said collector chamber is arranged between the trough-shaped chamber and the corner.
(FR)
L'invention concerne une installation (1) constituée de piles à combustible haute température (11) et d'une gaine multicomposant (4, 12, 13) formant un empilement de piles (5). Des chambres (7) orientées axialement, destinées à une post-combustion, sont situées entre la périphérie de l'empilement (5) et une zone extérieure de la gaine. Une structure bloquant les chambres comprend une cage (40), de type corset, dont la section perpendiculaire à l'axe de l'empilement se présente sensiblement sous la forme d'un quadrilatère régulier. Une chambre de post-combustion est associée à chaque angle de ce quadrilatère. Des forces élastiques radiales agissent sur chaque chambre à partir des angles, ce qui a pour effet de comprimer les arêtes d'étanchéité (75) de la chambre sur des bandes d'étanchéité (751) entre la chambre et l'empilement. Les arêtes d'étanchéité forment un bord fermé d'un espace en forme de cuvette qui est raccordé par l'intermédiaire d'un étranglement (73) à un canal collecteur axial (72) pour les gaz de combustion (30). Ce canal collecteur est placé entre l'espace en forme de cuvette et l'angle.
