Abstract
A honeycomb body assembly, in particular a catalyst carrier body, comprises at least one electrically heatable honeycomb body having layered metal sheets forming a stack with a plurality of channels through which a fluid can flow. The metal sheets have a thickness of about 0.03 to 0.12 mm. The honeycomb body is electrically subdivided with regard to its cross-section and/or in its axial direction. At least one electric current path is formed through the metal sheets with an electric resistance of between 0.01 and 2 .OMEGA.. The resistance, which is dependent on the temperature, can be used for monitoring and regulating the honeycomb assembly.
