Abstract (en)
[origin: DE19639633A1] The invention concerns a structure (1), that can be cross flown by a fluid, specially a honeycomb body for an exhaust gas catalyst. Said structure has an inflow area (2) and an outflow area (3) having channels to be cross flown by a fluid. The disclosed structure has near the inflow and the outflow areas (2, 3) respectively a section (6, 10) with reduced heat conductivity, which has recesses (7, 9) formed in the wall of at least some channels (4).
