Patent ID: 8574500

Claim:
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 resilient and/or compressible material selected from the group consisting of: elastomers, thermoelastic polymers, thermoplastic polymers, and graphite, and wherein the thickness of the flat seal ( 8 ) is at least the ratio between the extent of the irregularities of the plates and the maximum deformability of the flat seal ( 8 ).
