Component made of a stack of ceramic plates

A component comprising a multiplicity of plates (1) stacked on one another, at least one of which consists of a ceramic material and in which by means of webs (2) a channel region is formed of fluid flow guide channels (3), which are in flow communication with inlet and outlet openings (4, 5, 6, 7),

• the stack of plates being connected with a force fit by means of a clamping device and a flat seal (8) respectively being arranged between the individual plates (1) of the stack,
• wherein the flat seal (8) covers both the regions encompassing the channel region and the inlet and outlet openings (4, 5, 6, 7) as well as, at least partially, the web upper sides of the webs (2) forming the channels,
• wherein the flat seal (8) comprises a material having a lower Young's modulus than the ceramic material and wherein the material of the flat seal (8) is selected from the group consisting of:
• elastomers, thermoelastic polymers, thermoplastic polymers, and graphite,
• wherein the thickness of the flat seal (8) is the ratio between the amount of the directional distortion of the plates (1) and the maximum deformability of the flat seal (8), and
• wherein the maximum deformability of the flat seal (8) is the difference between an initial thickness (hD1) and a main load thickness (hD3) divided by the main load thickness (hD3), wherein the main load thickness (hD3) is the thickness of the flat seal (8) after applying a main load.
