preparing a substrate made of metal alloy of chromia-forming type, a base element of which being iron or nickel, the substrate having two main flat faces;
tape casting a thick ceramic layer, thereby producing a tape-cast thick ceramic layer;
locally removing at one or more locations of material of the tape-cast thick ceramic layer;
hot pressing a green thick ceramic layer tape; and
grooving the thick ceramic layer so as to delimit channels that are suitable for distributing and/or collecting gases,
wherein the locally removing is carried out before the hot pressing.
