A measuring arrangement for the analysis of gas components in gas mixtures, having at least one electrochemical solid electrolyte test cell with at least one cathode in a diffusion channel is exposed to a gas mixture. The use of several cathodes wired one behind the other makes possible selective analysis of individual gas components. At the first cathode, oxygen is selectively pumped off by the use of specifically oxygen-ion-conductive layers so that another component of the gas mixture can be analyzed by the following electrode.

An electrochemical sensor for ascertaining gas concentrations in gases, particularly in exhaust gases of combustion engines, includes an oxygen-ion-conductive solid electrolyte which is provided with electrode layers arranged at a distance from one another and with at least one resistance heating element that is separated from the solid electrolyte by an electrical insulating layer, a foil binder layer being provided between the electrical insulating layer and the solid electrolyte. At least one electron-conductive intermediate layer is provided between the electrode-side electrical insulating layer and the adjacent solid electrolyte.

The invention proposes a paste for welding ceramic materials to metallic contact surfaces or metals, which contains a noble metal, an aluminum compound, a silicon compound, and a compound selected from the group of the barium compounds, calcium compounds, and magnesium compounds. Along with these, a binder, a solvent, a softener, a thixotropic agent, and a dispersing agent can also be added to the paste. A paste of this kind is used to produce a welded joint between ceramic materials and a metallic contact surface, the paste preferably being printed onto the ceramic material. The ceramic material is then sintered with the paste, and then the metallic contact surface or a metal is welded on.
