Abstract (en)
[origin: WO2022109642A1] The invention relates to a burner device (10) for a fuel cell system (100), having a burner housing (20) with a burner inlet (22) for admitting a fuel/air mixture (BL) and a burner outlet (24) for discharging a burner exhaust gas/air mixture (BAL). The burner device additionally has a catalyst body (30) within the burner housing (20), comprising a catalyst cavity (32) into which the burner inlet (22) opens, wherein the catalyst body (30) is gas-permeable and has a catalyst surface (34) with an at least partly catalytic coating (36), and a bypass volume (40) is formed between the catalyst surface (34) and the burner housing (20), said bypass volume opening into the burner outlet (24). The catalyst body (30) additionally has a longitudinal axis (LA), and the catalyst surface (34) has a cross-sectional contour (QK) which deviates from a circular shape at least in some sections with respect to the longitudinal axis (LA).
