Problems solved by technology

[0005] The previously available measures of compaction have the disadvantage, however, that if the high-temperature-resistant insulator shrinks under conditions of pressure and high temperature, the compaction is not suitable for this shrinkage, so that the fuel cell stack Compression cannot be permanently ensured
[0006] Another disadvantage of this known pressing system is that the mounting of the pressing elements cannot be achieved in a way that facilitates assembly

Embodiment Construction

[0032] figure 1 with 2 A first embodiment of the housing according to the invention is shown, in which figure 1 shows the open state of the housing, while figure 2 The closed state of the housing is shown. The housing according to the invention comprises an outer enclosure shell 10 and an inner enclosure shell 12, said outer and inner enclosure shells being preferably made of insulating material. Further optionally, the outer enclosure shell 10 and / or the inner enclosure shell 12 are lined and / or coated with an insulating material on their outer sides. The two closure shells 10 , 12 are parallelepiped-shaped shells open at one end, which are dimensioned such that they nest into each other with an exact fit or without play. The outer closed shell 10 is provided with four hinged elastic clamps 14, and these four hinged elastic clamps are used as clamping devices. These hinged spring clips 14 are fixedly connected on the outside of the outer closure shell 10, so that the ca...

Abstract

The invention relates to a housing for accommodating at least one fuel cell stack (16; 116; 216; 316; 416), comprisign a first housing shell (10; 110; 210; 310; 410) and a second housing shell (12; 112; 212; 312; 412), wherein the first and the second housing shells may be tightened against each other by means of a fastening device such that the fuel cell stack to be accommodated is loaded in the stacking direction thereof by means of the elastic forces of the fastening device.

Description

technical field [0001] The invention relates to a housing or enclosure for receiving at least one fuel cell stack, comprising a first enclosure and a second enclosure. [0002] Furthermore, the invention relates to a system comprising such a casing and a fuel cell stack. Background technique [0003] A SOFC fuel cell system (SOFC="Solid Oxide Fuel Cell") consists of a plurality of components, for this purpose the converter, the afterburner and the SOFC fuel cell stack etc. These components operate at temperatures of approximately 900°C. [0004] It is known that SOFC fuel cell stacks are produced under defined pressure (compression force) conditions. Compaction of the stack is ensured by temporary clamping forces during manufacture, storage and installation into the system. A possible measure for stiffening or compacting a fuel cell stack is known, for example, from patent publication DE 10308382 B3. [0005] The previously available measures of compaction have the disad...
