Abstract
A catalyst system and a recombination device for recombining hydrogen and oxygen, and a method for operating a catalyst system, are used in particular for a nuclear power station. The catalyst system includes a metallic carrier plate which is coated with a first and a second catalytic noble or precious metal. The carrier plate has a low mass and is constructed with high heat conductivity. It is coated in a first zone with the first catalytic noble or precious metal and in a second zone with the second noble or precious metal. The first and second zones are preferably located on the same side of the carrier plate. Platinum and palladium are preferably used as the noble or precious metals. The palladium serves for early ignition, and the platinum ensures good activation along with sufficient catalyst poison resistance.
