Abstract
An exhaust aftertreatment device includes a catalyst assembly having an electrically conductive carrier matrix and first and second electrodes. The first and second electrodes have terminals attached on opposing sides of the catalyst assembly to be electrically connected to each other through the carrier matrix and configured to generate heat. A first elongate heat sink extends axially along the first electrode and is configured to absorb a portion of the heat to mitigate formation of hotspots.
