Abstract: The invention relates to a process for producing a catalytic component on a metallic or ceramic support for a fuel cell system, in which the catalytic component is applied to the metallic or ceramic support in at least one layer. This at least one layer contains at least one hydrophobic material component, which is applied together or alternately with at least one catalytically active material component in one process step. The invention also relates to a catalytic component, which is applied to a metallic or ceramic support, for a chemical reactor in a fuel cell system, and to methods of using the catalytic component.

Abstract: A method for shortening the cold starting time of a CO oxidation catalytic converter in a vehicle with an integrated fuel cell system. According to the invention, gas components which delay the start are removed from the reformate gas of the gas-generating system using an adsorber during the cooling-down phase after the vehicle has been switched off.

Abstract: A process for producing a coated, structured heat exchanger plate for a reactor in a fuel cell system comprises application of a catalytic component in at least one layer by means of pad printing, exclusively in the recesses and/or the flanks of the heat exchanger plate.

Abstract: A fuel cell system for a motor vehicle, with at least one fuel cell and with a gas generation system, has at least one device for cleaning the air that is taken in. The device is arranged in an area in front of the cathode chamber of at least one fuel cell and/or in an area in front of a gas generation system, and contains at least one element for adsorption of ions and/or hydrocarbons.

Abstract: A sealed rocker switch includes a button having a lever. A coil spring coaxial with the lever and enclosing a portion of the lever forces a plunger against an actuator that rocks to place a spring blade in contact with blade contacts to operate the switch. The blade contacts are snapped into the case of the switch to maintain the blade contacts in a desired position, and are potted with a potting compound to make a seal. The actuator may be shaped in one of several ways to provide maintained contact, momentary contact, or a combination of these. A groove in the lever supports an O-ring against the case to seal the switch at the button end.
