Abstract

There is provided a start-up catalyzer for catalyzing exhaust gas from an internal combustion engine in which flat and corrugated sheets are disposed in alternating relation. Some of the flat sheets have an electrically conductive resistance-heating layer which may be catalytically active and in form of a plurality of rosette-shaped conductive loops connected in series.
