30. A catalyzer, comprising:
a plurality of plane sheets arranged superposed and spaced apart from each other in a stack, each of the plane sheets having a top side and a bottom side, each two successive plane sheets defining a channel that extends parallel to a flow direction, the channel being delimited by the plane sheets;
a corrugated sheet having a plurality of ridges and grooves disposed within the channel, the ridges being connected to the plane sheets of the channel and the grooves being substantially parallel to the flow direction;
a catalytic coating disposed on a predetermined section of at least one of the top side and the bottom side of each plane sheet and defining a coated section which only partially covers the top side and/or the bottom side, the coated section positioned opposite to an uncoated section of the plane sheet; and
a catalytic coating disposed on at least a portion of the corrugated sheet, the portion defining a coated section of the corrugated sheet;
wherein at least a portion of a heat radiation emitted from the catalytic coating is absorbed by the uncoated section of the plane sheet.
