Abstract
Electrically conductive honeycomb structures are provided for use as catalytic converters, pre-heaters for catalytic converters, or particulate filters. The honeycomb structures are composed of subunits which are arranged to produce a serpentine conductive path through the honeycomb. The serpentine path gives the honeycomb an increased electrical resistance so that elevated temperatures can be achieved with less current. The subunits allow the serpentine current path to be produced without any slitting or cutting of the honeycomb.
