Abstract
There is provided a core element for an electrically heatable catalytic converter, and an electrically heatable catalytic converter containing the same, the core element being characterized by a corrugated thin metal foil strip, preferably herringbone corrugated, and in laminar relationship therewith, a flat thin metal foil strip of either stainless steel or brazing metal, or a combination of both, the flat thin metal foil strip having a width less than the width of the corrugated thin metal foil strip. The strips are then spirally wound, or accordion folded to form a monolith, and suitably connected to a voltage source to supply electrical power to the unit.
