Abstract: A heating member for a vehicle exhaust gas purification device includes an electrically conductive outer peripheral frame that has a geometric center and is symmetrical about an axis. An electrically conductive central support is centered on the geometric center, and a perforated heating grid is centered on the geometric center. The heating grid extends between the electrically conductive central support and the electrically conductive outer peripheral frame. The heating grid is formed of a plurality of strands connected by nodes, with the plurality of strands delimiting openings there between.

Abstract: An exhaust gas purification member comprises an annular substrate centered on a central axis, a peripheral electrode alongside and against an outer cylindrical face of the substrate, and a central electrode alongside and against an inner cylindrical face of the substrate. The substrate is made up of an electrically conductive material and includes a plurality of intersecting walls defining longitudinal cells therebetween and that each emerge in an upstream face and in a downstream face of the substrate. These intersecting walls are covered with a catalytic composition and each wall extends from an outer cylindrical wall of the substrate, defining the outer cylindrical face, to the inner cylindrical wall of the substrate, defining the inner cylindrical face.
