    摘要: The present invention pertains to an electrically heatable honeycomb element (1) for the catalytic conversion of gases, in particular exhaust gases from an internal combustion engine. The element has a plurality of channels (4) which can be permeated by a fluid and is electrically divided up along its cross-section and/or axial extension, in particular meandering and/or helical. At least two approximately half-shell current distributing structures (6, 7) are provided on the outer jacket surface (5) and are completely isolated by an annular gap from a jacket pipe (20), each current distribution structure (6, 7) having at least one collar (8) extending radially outwards or inwards around the circumference. This design prevents deformation of the current distribution structures (6, 7) at high operating loads.
