Abstract:
A method is provided for operating a device having at least one electrically heatable honeycomb body through which an exhaust gas can flow. The electrically heatable honeycomb body has at least one current distribution structure to which a plurality of short, successive voltage pulses are initially applied during activation, before a constant heating voltage is applied to the current distribution structure to heat the honeycomb body. A suitable device for the catalytic conversion of exhaust gases in an exhaust system is also provided.
