Abstract
The invention relates to a honeycomb ( ), particularly a catalytic converter substrate, with a honeycomb structure comprising a large number of ducts ( ) running in the longitudinal direction of the honeycomb, through which a fluid can flow, where the honeycomb possesses foil layers ( ) arranged one above the other. In order to create a honeycomb permitting high efficiency of the catalytic conversion reactions with low thermal inertia, as well as inexpensive manufacture, it is proposed to provide ducts ( ) whose cross-sectional dimension in a first direction is several times the cross-sectional dimension in another direction. In particular, the ducts can extend over the entire width of the honeycomb. In order to stabilise the honeycomb, stiffening elements ( ) can be provided, which are either integrated in the foil layers or separate (FIG. ).
