ABSTRACT:
A heating element for heating fluid flowing therethrough, including an electrically conductive honeycomb structure, electrodes electrically connected to the honeycomb structure for applying an electric current to the honeycomb structure, wherein the honeycomb structure has a front region which is adapted to heat more quickly than a back region of the honeycomb structure. To this end, the honeycomb structure may include at least one gap for obstructing electric current flow, the gap extending through the partition walls and terminating before reaching the front end of the honeycomb structure. Alternatively, the front region may be heated more quickly than the back region by providing at least one depression formed the back end of the honeycomb structure, such that the front region extends from a terminating end of the depression toward the front end of the honeycomb structure. A catalytic converter incorporating the heating element is also provided.
