Abstract: One aspect relates to a method for producing a sensor, in particular a temperature sensor, with at least one electrically conductive layer and at least one additional layer, in particular a passivation layer and/or an insulation layer. According to one aspect, the electrically conductive layer and/or the additional layer, in particular the passivation layer and/or the insulation layer, are produced by aerosol deposition (aerosol deposition method, ADM).

Abstract: An electrical resistor has a resistance layer containing platinum or a platinum group metal, which is applied to an electrically insulating surface of a substrate, wherein the resistance layer is constructed as a thin layer element and is made of a physical mixture of finely dispersed ceramic and metal. Preferably, the ratio of finely dispersed ceramic to metal lies in a range of about 5 to 50% by weight. Preferably, the finely dispersed ceramic is selected from SiO, Sio2, Ta2O5, MgO, Al2O3, and mixtures thereof. The resistor is used as a reference resistor in a sensor (temperature sensor) together with a temperature-dependent measuring resistor, wherein both resistors are arranged on a common substrate.

Abstract: A high-temperature fuel cell includes two chambers to be acted upon by a reaction gas. A partition is formed of an oxygen-conducting ceramic material with a given coefficient of thermal expansion. The partition separates the chambers from one another and defines outer walls of the chambers opposite the partition and side walls of the chambers contacting the partition. Electrodes are each disposed at a respective side of the partition. The outer walls are formed of a soft metal sheet having at least one corrugation for compensation of expansion and the side walls are formed of a material with the given coefficient of thermal expansion. A high-temperature fuel cell stack may include a plurality of series-connected high-temperature fuel cells.
